Abstract

Proposed as initial activation experiments for photonuclear research with $\gamma$-quanta at energies $E_{\gamma}\leq 40$ MeV are those using a source of backward Compton scattered laser radiation on accelerated electrons, which is currently under development. These experiments are crucial both for refining the techniques of tuning and monitoring such $\gamma$-beams, and for investigating the excitation of pygmy and giant resonances in nuclei at $E_{\gamma}$ near the threshold of the ($\gamma,n$) reactions, as well as the multiplicity of photoneutrons during the de-excitation of E1 giant resonances at $E_{\gamma}$ above the threshold of the ($\gamma,2n$) reactions.

关于在 $$\boldsymbol{E}_{\gamma}}\boldsymbol{\leq 40}$ MeV 的后向康普顿散射中 $${\gamma}$ 光子核反应的活化研究

摘要作为在能量为 $E_{\gamma}\leq 40$ MeV 的情况下使用 $\gamma$-quanta 进行光核研究的初始活化实验，建议使用目前正在开发的加速电子上的后向康普顿散射激光辐射源。这些实验对于完善调谐和监测这种$\gamma$-光束的技术，以及研究在($\gamma. n$) 反应阈值附近的($E_{\gamma}$处激发原子核中的侏儒共振和巨共振都是至关重要的、($\gamma,2n$)反应阈值之上的 $E_{\gamma}$ E1 巨大共振的去激发过程中的光电子倍率。
