Abstract

Procedures are described to identify simultaneously the mass and charge of projectile-like fragments produced in damped heavy-ion reactions and derived from data recorded with a ΔEE time-of-flight telescope. Corrections for the effects of particle emission from the primary reaction products are also discussed. The average properties of the resultant charge, neutron and mass distributions can be described by six parameters obtained from a two-dimensional Gaussian fit. These parameters, which are a function of kinetic energy damping, summarize the properties of nucleon exchange in the damped process. After the effects of experimental resolution (in two dimensions, charge and mass) and the effects of binning of the data have been taken into account, most physically relevant quantities of interest and their uncertainties can be calculated with the formulas presented.
