The production of alpha particles in photonuclear reactions on 65Cu, 115In, 92Mo and 207Pb targets in the beam of accelerated electrons with energy of 21 and 40 MeV was studied. The experiments were run on the Linear Electron Accelerator NLA (The Yerevan Physics Institute). The measurement results represent the yields of reactions studied as functions of the mass number of nuclei and the photon energy. The data obtained enable one to suggest a change in the mechanism of alpha particle photoproduction with increasing energy of incident photons and target mass.

21 MeV和40 MeV光子能量下光核反应中α粒子产生的研究

研究了在具有21和40 MeV能量的加速电子束中在65 Cu,115 In,92 Mo和207 Pb靶上进行光核反应时产生的α粒子。实验在线性电子加速器NLA(埃里温物理研究所)上进行。测量结果代表所研究反应的产率,其为核质量数和光子能量的函数。获得的数据使人们提出了随着入射光子能量和目标质量增加,α粒子光产生机理的改变。
