XXXIII. 8 Li emission from proton induced disintegrations at 950 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.
