Recently the process of emission of multiply-charged fragments from nuclear interactions has been the subject of a series of investigations. The advent of powerful accelerators has enabled the study of the process at various energies of the incident particle. Protons of energy ranging from 350 Mev to 9000 Mev have been enployed to irradiate nuclear emulsion. the disintegrations recorded in the emulsion are then analysed. Some of the features of the fragment production have been found to change drastically. This has prompted this investigation which employs a primary energy much higher than the already studied range. The Li8 fragments emitted in the disintegrations produced by 28 Bev protons in nuclear emulsion have been chosen for analysis.
