Abstract
A combination of ion chambers and Cerenkov radiators similar to the Heavy Nuclei Experiment flown on HEAO-3 was calibrated at the Bevalac heavy-ion accelerator using beams of Mn-25 nuclei at kinetic energies up to about 1700 MeV/nucleon and Au-79 nuclei up to about 1000 MeV/nucleon. The data show only a small deviation (about 2-3 charge units at Au) from the Z^2 scaling used previously (Binns et al., 1981, 1982, 1983) to analyze the HNE data. Although at lower energy, the calibration indicates that the published relative abundances of the _(50)Sn/_(56)Ba group and the published upper-limit actinide abundances are not likely to be significantly affected by non-Z^2 effects.
Additional Information
This calibration, like so many others, was made possible by unstinting assistance from Hank Crawford and many others at the Bevalac. We also wish to single out Mel Flores and Fed Lothrop for thanks. We are grateful for advice and assistance from W. E. Althouse, A. Buffington, and J. Epstein.
