摘要

摘要讨论了利用相对论正电子飞行湮灭过程中形成的轫致辐射和准能量光子束获取光核反应截面信息的方法的特点。这些方法提供了核激发能量高达 \({\sim}40\) MeV 的绝大多数数据。研究表明，这些实验结果在绝对值和形状上的重大分歧是由于这两种方法的某些缺陷造成的。通过使用在后向康普顿散射过程中形成的光子束，可以在一定程度上消除这些缺陷。

Photonuclear Experiments: From Bremsstrahlung to Backward Compton Scattering Photons

Abstract

The features of methods for obtaining information on photonuclear reaction cross sections using beams of bremsstrahlung and quasimonoenergetic photons formed during the in-flight annihilation of relativistic positrons are discussed. These methods have provided the vast majority of data in the nuclear excitation energy up to \({\sim}40\) MeV. It is shown that significant disagreements between the results of such experiments, both in absolute value and shape, are due to certain shortcomings of both methods. These shortcomings can be to a certain extent eliminated by using beams of photons formed in the processes of backward Compton scattering.
