Fission fragment mass reconstruction from Si surface barrier detector measurement

Abstract

A method for plasma delay and pulse-height defect corrections for Si surface barrier detectors (SBD) is presented. Based on known empirical formulae, simple approximations involving the measured time-of-flight (TOF) and energy of the ions were found and a mass reconstruction procedure was developed. The procedure was applied for obtaining the fission fragment mass and angular distributions from the $^{64}$ Ni+$^{197}$Au reaction at 418 MeV and 383 MeV incident energy using an array of eight SBDs.Comment: 3 pages, 1 table, 3 figures, submitted to NIM A ; 4 pages, 1 table, 5 figures, added discussion and figure
