Friends, as we know, and we also studied schools, protons are certainly very small, their size is less than two trillionths of a millimeter, precise techniques are needed to draw the radius on the proton.When the researcher set fire to a beam of electrons on a hydrogen atom, the nucleus consists of a single proton.And because of this, electrons bounce off the proton at an angle, and thereby determine its size. Friends are another strategy, in which the size of the proton depends on spectroscopy, if we talk about spectroscopy, it will be irradiated at different frequencies. Can measure the intensity, it emits an object.When the scientist excited the electron of the hydrogen atom, and they It has seen a jump from one energy state, and then he looked carefully at the frequency of required radiation for keeping this infection,and scientists have some gap in between found.Scientists now believe that the gap between energy levels depends on the size of the proton.
In order to reduce the measurement size of the proton, scientists have, during 1950, performed measurements using two methods, which set the radius of the proton to an apparent 0.88 womanometer. And then to reduce the size of the proton, even in 2010, researchers led by Randolph Pohl tried to do something different, the researchers used the spectroscopic method, and they found, with a special muonic "hydrogen": And instead of an electron, it is a muon, and a particle in the atom, which has about 200 times the mass of the electron. This is because, friends, that The prion holds the proton more tightly than an electron, and its energy level is more sensitive to the size of the proton, and provides more accurate results. Friends Also the researchers have studied the particular transition , (In which the muon jumps from its first excited state to another) and moves more directly towards the proton radius than in other transitions They were all surprised when Pohl and his team found a low value of the radius, as researchers had pegged it at 0.84 woman-kilometers outside the range of sizes, established by earlier measurements.
The result of Pohl's proton size knocked out of the head in high gear, guys, was there really something wrong with earlier experiments by researchers? Or how protons interact with them compared to their behavior around electrons. Researchers were unaware of yet unknown physics. Researchers believe that When there is a discrepancy in the data, it really gets people excited. When Pohl first presented the results regarding Proton's size, Hessels took Pohl's findings as a personal challenge, and he worked to repeat the experiment again, with Eric Hessels being a key member of the York team. Hessels used regular hydrogen - just below the particular energy-level transition - to observe that the muon jumps from its first excited state to the second, and this jump is known as the Lamb shift. Physicist Willis Lamb first measured in 1940. An accurate measurement of the lamb's shift into hydrogen regularly guaranteed to reveal something of interest. If it matches the first, larger value, or else it may signal for new physics; Or if it matches a lower value, it will help solve a decades-old puzzle, and reduce the size of the proton.
Friends Hessel and his team determined the radius of the proton to be 0.833 womanometers, a measurement that agrees with Pohl's measurements, it took Hessel eight years to find the answer. Friends Hessel used to say that this was a more difficult measurement than anticipated, and more difficult than any other measurement we have done in our laboratory. Hessel and his team used radio-frequency radiation to excite hydrogen atoms. Sciatico republished the results. Friends, it is still unclear why previous researchers' experiments generated a large value for the radius of the proton. Researchers suggested that errors in experimental design are a possibility. There seems to be yet another possibility in the measurement of the radius of a proton by Hessels, that this unknown physics still prevents the results.
Friends say Hessel, that there is a consensus around the low value for the proton radius. Because the accuracy and proximity of York and the 2010 data shows, there are many measurements right now, and they begin with muon-hydrogen measurements. Hessels states that these measurements decrease, but do not disappear: this measurement of Hessels is the best spectroscopic measurement obtained with normal hydrogen.Friends, if we look at Pehl's measurement of muon-hydrogen method it is more accurate due to more sensitivity. We can guess from both these discoveries, that there is still room for more sensitive experiments. Two protons still have other secrets,So we can say that Proton has not given up yet. Friends, we all know that both protons and neutrons are made up of three quarks bound by strong atomic forces, and the exact nature of this bond is difficult to explain, says Nilanga Liananz, a physicist at the University of Virginia.We are all made up of protons, say Lianz, who solved the proton radius puzzle through electron-scattering experiments at Jefferson Lab in Virginia. He says that 99.9 percent of our mass - of everything in the universe - comes from protons and neutrons. And he believes that the proton radius is an important benchmark quantity, and is a very important particle, and to understand it Needed.
