Summary
SPIT is an adaptation by John Wild [Wild 1988] of a neutron evaporation code that has been in circulation around LBNL and LLNL. It is a program for calculating fusion product cross sections for reactions that de-excite through neutron emission. It was originally written in FORTRAN for the VAX microcomputer. It is related closely to another neutron evaporation code JORPLE written by Jose Alonso [Alonso 1974]. SPIT uses a different set of potentials and does a better job of reproducing the excitation function shapes than JORPLE, though both predict approximately the same excitation peak energy. The main difference [Haynes 1988] between the two programs is that JORPLE uses a standard Coulomb potential and the Woods-Saxon potential, while SPIT uses a Bondorf, Sobel, and Sperber coulomb potential [Bondorf 1974] and the Bass proximity potential [Bass 1974]. Our group, the Heavy Element Nuclear & Radiochemistry Group, here at LBNL has made extensive use of this code for estimating reaction cross sections for experiments that are to be performed at the 88-Inch cyclotron. It requires no calculation parameters aside from the Z and A of the projectile and target nucleus, and this feature has allowed us to use it in a consistent manner for experiments here for over ten years. The cross sections that are calculated with SPIT are consistently within an order of magnitude of those experimentally observed.
