Abstract

New experimental data on the multifragmentation of carbon nuclei that is initiated by the photoproduction of neutral pions and eta mesons are discussed. The novelty is associated with the exclusive character of the processes being studied, in which case a determination of partial meson-photoproduction reactions is followed by an analysis of complementary particles for coincidence. The experiment being discussed was performed by the GRAAL (GRenoble Accelerateur Anneau Laser) Collaboration in a beam of 500- to 1500-MeV Compton photons. The possibility of performing new experiments within the BGO-OD Collaboration (Bonn, Germany) is considered. A new method for studying the interaction of short-lived mesons with nuclei on the basis of detecting cascade recoil nucleons is proposed.

中性光子介子光产生中的核级联动力学

摘要

讨论了由中性介子和η介子的光产生引发的碳核多片段化的新实验数据。新颖性与正在研究的过程的排他性有关，在这种情况下，确定部分介子光生反应后，将分析互补粒子的巧合。所讨论的实验是通过GRAAL（格勒诺布尔Accelerateur Anneau激光）协作在500至1500 MeV康普顿光子束中进行的。考虑了在BGO-OD协作组织（德国波恩）内进行新实验的可能性。提出了一种在检测级联后坐核子的基础上研究短寿命介子与核相互作用的新方法。
