Abstract

Abstract Energy loss of 252Cf fission fragments in P-10 gas (90% Ar + 10% CH 4) at different pressures has been measured using a hybrid ΔE− E R detector telescope. The data were fitted to a polynomial function and the differential or specific energy loss (d E/d x) along the range of the fission fragments was determined for different fragment kinetic energies. The experimentally measured energy-loss data for most probable light and heavy fragments are compared with calculations using different available energy-loss expressions based on the Bethe energy-loss formula.
