XXXIII.8Li emission from proton induced disintegrations at950 mev

Abstract

G5 plates exposed to 950 mev protons were are ascanned and fifty ⁸Li “Hammer stars” discovered. They were divided into stars representing light and heavy nuclei disintegrations. In the case of light element stars the energy and angular distributions of the ⁸Li fragment indicate that it is the residual nucleus after a light element breakup. For heavy nuclei stars the mechanisms of direct knock-on and evaporation can be excluded. The simplest hypothesis is that the fragments are ejected as part of the cascade process.
