A heavy ion identification scheme based on semiempirical range-energy calculations

Particle identification schemes for heavy ions have been tested using the semiempirical range-energy calculations of Northcliffe and Schilling as primary data. A new scheme is suggested in which the particle identifying output (PIO) may be calculated from the relationship PIO = mET + b, where ET is the total energy of the particle and m and b are functions of ΔE/ET, the ratio of the energy loss in the front detector of a detector telescope to the total energy of the particle. Functions for determining m and b are generated using the range-energy tables. The scheme has been compared with other techniques and found to be useful for ions Z≥4.
