An Accelerator Test of Semi-Empirical Cross-Sections

Abstract

We compare experimentally measured yields of isotopes of elements from _(12)Mg to _(19)K resulting from the fragmentation of ^(40)Ar with calculated yields based on semi-empirical cross-section formulae. The measurements, made at the LBL Bevalac using a beam of 287 MeV / amu ^(40)Ar incident on a CH_2 target, achieve excellent mass resolution (σ_m ≤ 0.2 amu) through the use of a Si(Li) detector telescope. The general agreement between calculation and experiment is good (rms difference ≃ 24%), but some significant differences are reported.
