摘要

给出了$d+{}^{1}\textrm{H}\to p+p+n$反应的研究结果。在莫斯科国立罗蒙诺索夫大学Skobeltsyn核物理研究所的U-120加速器上进行了氘核束流能量15.3 MeV的运动完全实验。从单线态$pp$分裂出来的一个质子和一个次级中子被巧合地记录下来。研究结果确定了$pp$相互作用的低能特性，即虚单重态$pp$的能量值和对应的$pp$散射长度值。

Determining Low-Energy Characteristics of the $\boldsymbol{pp}$ Interaction in the ${d+{}^{1}}\mathbf{H}{\to p+p+n}$ Reaction

The study results of the $d+{}^{1}\textrm{H}\to p+p+n$ reaction are presented. A kinematically complete experiment with using a deuteron beam energy of 15.3 MeV at the U-120 accelerator of the Skobeltsyn Institute of Nuclear Physics of the Lomonosov Moscow State University was carried out. A proton from the breakup of the singlet $pp$ state and a secondary neutron were registered in coincidence. As a result of the study, the low-energy characteristics of $pp$ interaction, namely, the energy value of the virtual singlet $pp$ state and the corresponding value of the $pp$ scattering length were determined.
