Measurement possibility of small amplitudes contribution in the reactions of two-particle ⁴He photodisintegration
The two-body photodisintegration of 4He was investigated. The dependence of expansion coe±cients hard error on the histogram bin, the angle measurement precision and coordinate position where fitting function is calculated, was studied. It is shown that the logarithm of the relative error in coe±cie...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The two-body photodisintegration of 4He was investigated. The dependence of expansion coe±cients hard error on the histogram bin, the angle measurement precision and coordinate position where fitting function is calculated, was studied. It is shown that the logarithm of the relative error in coe±cients is in the linear dependence on the logarithm of a number of events. The relation between the number of events, necessary for obtaining the relative errors of 5%, 10% and 20%, and the value of coe±cients was found. The results are compared with the experimental data. In the future experiment the estimation of the upper limits in coe±cients can be set as a main goal. |
