Abstract

The energy spectra were analyzed for correlated pairs of single-charged particles emitted at an angle of 180° by the nuclei of a “live” target (an analogue of the ²⁸Si target) during the absorption of stopped π⁻ mesons. The information obtained with the help of the live target is interesting for testing hypotheses about the mechanisms of formation of complex particles. Data analysis made it possible to detect complex particles, both of cluster (direct) origin and formed because of secondary intranuclear interactions.

π介子在活靶上吸收过程中相关带电粒子的形成

分析了“活”靶核（类似于28Si靶）在吸收停止的π−介子时以180°角度发射的相关单带电粒子对的能谱。在活靶的帮助下获得的信息对于检验关于复杂粒子形成机制的假设是有趣的。数据分析使检测复杂粒子成为可能，无论是簇（直接）起源还是由于次级核内相互作用而形成的。
