Nature of problem:
Interactive program NUCFRAG, presents an algorithm for an abrasion/ ablation model of heavy ion fragmentation which includes a second order correction for the surface energy term and addition of photonuclear dissociation to provide reasonable representation of the present elemental fragmentation cross sections.
Using the Weizsacker-Williams method of virtual quanta, the photodissociation fragmentation cross sections are calculated and added to the nuclear fragmentation cross sections generated by an abrasion/ ablation model of heavy ion collision.
The photodissociation cross sections are calculated for one nucleon removal only (either a proton or neutron). The nuclear interaction fragmentation cross sections are not calculated for target fragments and peripheral collisions with Delta A < 0.5.
On C.D.C - Cyber/750 at NASA Langley Research Center, compilation takes about 20-30 seconds, while execution is about 60-90 seconds.
