Some characteristics of high energy proton–nucleus collisions

Abstract
The variation of emission frequency, f, of fast protons, deuterons, tritons, He-nuclei, and slow pions, produced in 24 GeV/c proton interactions with Ag and Br nuclei of nuclear emulsion with , , , and has been investigated. For all the particles has been observed to increase linearly with , , and . The variation of with has been found to be linear for slow pions, protons, and deuterons, whereas it varies as in the case of tritons and He-nuclei. The frequency of slow pions has been determined to be ~(0.33 ± 0.04), which is ~ 7.8% of the mean number of grey tracks. Further, the emission of low energy pions has been observed to be more frequent in relatively heavier stars.
