Ultra-Dimensional Technology Era

"My experiment has something to do with parity violation, and the specific results will be known tomorrow."

Parity non-conservation Zhang Tingyu racked his brains but couldn't think of any good research on π neutrinos and parity non-conservation.

But geniuses are always unconstrained. He has been with Huang Mingzhe for so long, so he naturally knows that the young man in front of him can be said to be the uncrowned king of physics today.

Naturally, he couldn't figure out what Huang Mingzhe was thinking, and could only wait for the results of tomorrow's experiment.

4 month 11 day.

Just after dawn, Zhang Tingyu, who tossed and turned all night, began to get busy with panda eyes.

And Ye Qi, the base manager of Base 006, also appeared in the laboratory today.

At nine o'clock in the morning, the experiment started again.

But this time, the experimental objects placed in the direction of the flow of π neutrinos are no longer those little white mice and chimpanzees.

The staff wearing the special protective clothing of Siwei Society installed more than a dozen instruments in the direction of the flow of π neutrinos.

Then two staff members carefully opened a special lead alloy box, and took out a black metal hemispherical object from the box.

Although the hemisphere is only the size of a bowl, the staff held it very hard. This is a piece of highly enriched uranium, the concentration of which has reached 99.99%.

The staff carefully put the uranium block on the detector platform and fixed it.

On one side, there are as many as twelve similar lead alloy boxes, in which there are not only uranium blocks but also plutonium blocks, and these uranium blocks and plutonium blocks are fixed on each experimental platform in turn.

"What's the level of nuclear radiation?" Huang Mingzhe also wore special protective clothing all over his body.

"It's still the level of normal uranium and plutonium radiation." Zhang Tingyu replied.

Huang Mingzhe looked at the data of each instrument, and told Zhang Tingyu: "Deputy Zhang, the experiment can start, just as we said yesterday."

"no problem."

After a while, the laboratory was running again. The laser beam of the laser was held on the carbon ions, jumped and amplified through the stepped mirror, and finally collided violently in the collision chamber.

Then there is the neutrino reflector, which adds high energy to neutrinos, and turns π neutrinos into high-energy π neutrinos.

But this time after the high-energy π neutrinos are emitted.

"How is it possible!" Zhang Tingyu exclaimed.

Chapter 144 Parity Completion

At this moment.

There was dead silence in the control room of the laboratory. Except for Zhang Tingyu who was startled, everyone else stared at the rows of computer screens in dumbfounded.

At the moment when the flow of high-energy π neutrinos brushed those uranium and plutonium blocks, all the radiation detectors and neutron detectors monitoring the uranium and plutonium blocks instantly changed to the ambient radiation value.

Zhang Tingyu, who regained some sanity, quickly ordered: "Replay the data just now."

"it is good."

The researchers quickly retrieved the data on the computer. Looking at the data on the computer, the results of 12 radiation detectors and 12 neutron detectors were exactly the same.

Sure enough, they were not mistaken. When the high-energy π neutrinos flowed over the uranium and plutonium blocks, the radiation of the uranium blocks and plutonium blocks instantly dropped to the ambient radiation level, and the number of neutrons returned to zero directly.

The same is true for the six uranium blocks and the plutonium blocks.

Zhang Tingyu's mind was churning. Could it be that the high-energy π neutrinos have an interference effect on the detector? If it is interference, the radiation detector cannot display the normal environmental radiation dose.

Among the people present, except for Huang Mingzhe who had already expected this result, the rest were laymen such as Ye Qi who didn't know what to do.

"Deputy Zhang."

Zhang Tingyu, who was in deep thought, suddenly woke up.

"Boss Huang, what are your orders?"

"Continue to collide."

Zhang Tingyu thought for a while and replied: "If the current power is used, the power supply system of our base can support the continuous collision for 10 to 15 minutes at most."

"Then continue the collision for 5 minutes first."

"it is good."

The experiment started again, but this time high-energy carbon ions continued to collide in the collider, and a steady stream of π neutrinos were excited.

With the boost of the neutrino reflector, the high-energy π neutrinos continuously wash away the uranium and plutonium blocks.

The data from the detectors connected to the screen showed that at this moment the uranium and plutonium blocks had lost their radioactivity.

Judging from the detection screen of the high-precision infrared camera, the temperature of the uranium and plutonium blocks dropped immediately after being washed by the high-energy neutrino flow. After about 3 minutes of washing, the temperature of the uranium and plutonium blocks became room temperature 24 degrees Celsius.

Originally, due to the high concentration, the radioactivity would make the uranium and plutonium blocks themselves slightly hotter than ordinary metals.

Under the high-precision infrared camera, the change of this temperature is very obvious.

From the current indications, the radioactivity of the uranium and plutonium blocks has really disappeared temporarily.

Zhang Tingyu turned his head curiously and asked, "Boss Huang, is this your theory that high-energy π neutrinos can suppress the decay of radioactive elements?"

Huang Mingzhe shook his head and replied, "It's not about suppressing radioactive elements."

"Not Inhibited"

"The law of parity violation tells us that there is a lack of asymmetry in the particles under the weak nuclear force, and this situation is the root cause of nuclear fission, that is, the beta decay of the atomic nucleus."

Of course Zhang Tingyu knows this. Under the weak nuclear force, the asymmetry is missing. During β decay, the nucleus undergoes the following three types of changes: X→ Y+e-+-ve (β-decay), X→ Y+e++ve ( β+decay), X+e-→ Y+ve (EC).

The decay energies released by the three types are: Qβ-=(mx-mY)c^2; Qβ+=(mx-mY-2me)c^2; QEC=(mx-mY)c^2-wi.

The one that emits positrons is called "positive beta decay" and the one that emits electrons is called "negative beta decay".

In positive beta decay, a proton in the nucleus turns into a neutron, releasing a positron and a neutrino at the same time; in negative beta decay, a neutron in the nucleus turns into a proton, releasing an electron and an antineutrino at the same time. neutrinos.

In addition, electron capture is also a kind of beta decay, called electron capture beta decay.

It can be seen from here that β decay is the embodiment of radioactive elements, and its root cause is the non-conservation of parity.

Thinking of this, Zhang Tingyu came to his senses: "Could it be that high-energy π neutrinos can make atomic nuclei temporarily maintain parity conservation?"

Huang Mingzhe nodded: "This is my theory, parity is completed."

Many people present are physicists, and they all know that the non-conservation of parity is the root of the existence of this universe.
