Abstract

Spectra of deuterons and tritons were measured at the absorption of stopped π — mesons on a “live” target (analog of the 28Si target). It is shown that the application of this method makes it possible to identify “direct” mechanisms of the formation of deuterons and tritons. An estimate of the proportion of these particles in total yields was obtained, which was ~ 30 %.
