In this experiment, the proton radius they measured was significantly lower than the value given by the International Committee on Scientific and Technological Data (codata), and the lowest was even as low as an astonishing 0.833 femtometers.

Even if the influence of energy level changes caused by electrons and protons outside the nucleus is removed, and the average number and error are taken, the radius value is still 0.± 0.00067 fm.

This experimental result caught the researchers at the time a little off guard. After all, the radius of the proton involved the base of the physics building.

After the results were released, more physicists pitched in

But since then, more spectroscopic experiments have further confirmed the small proton radius.

Experiments from various countries have shown that the radius of the proton should be smaller than before.

This chapter is not over yet, please click on the next page to continue reading! What is puzzling is that the proton radius obtained through scattering experiments always stays at around 0.8768 femtometers.

In other words, two different testing methods produced a 5% gap. This 5% gap is called the 'proton radius mystery'.

As of today, this mystery has finally been solved.

Of course, the premise is that Xu Chuan's calculation method is correct.

........

In front of the desk, Xu Chuan threw away the ballpoint pen in his hand, went to the bathroom, washed his face, and then threw himself on the bed. After a while, soft snoring sounded.

Both Android and Apple are available.]

In order to perfect the method in his hand, he had not slept much for more than thirty hours. The closer he got to the end of the mystery, the more excited he became, which was enough to resist physical fatigue.

Now that the result has finally been achieved, the thread hanging in my mind has finally been broken.

During this sleep, Xu Chuan slept from 4pm to 3am the next morning.

After getting up and washing up, Xu Chuan took a towel and wiped his wet hair while walking towards his desk.

The messy manuscript papers on the desk record what kind of trial this place has gone through before.

Picking up a piece of manuscript paper from the table, Xu Chuan's eyes fell on the final answer.

Judging from the results calculated based on current data, a small proton radius will be the answer to the particle physics community.

People have observed through numerous experiments that the charge radius of the proton is not as large as imagined.

And this also means that before 2010, the data observed by the entire physics community were wrong.

In other words, there was a huge error in their experimental process, which led to this result.

At present, he still doesn't know where this error comes from, but mathematics does not lie, and the problem does exist.

Thinking of this, Xu Chuan's lips raised a smile.

If this answer is released, I am afraid it will cause an uproar in the entire physics world.

After all, nowadays, many people think that the proton charge radius is a large radius, which is the number 0.8768 femtometers.
