GENERAL DESCRIPTION
TOTAL AND ELASTIC CROSS SECTIONS CALCULATED WITH ABACUS OPTICAL
MODEL CODE (REF.7)
THE INELASTIC,CAPTURE,N,P AND N-4HE CROSS SECTIONS CALCULATED WITH
CODE CERBERO (REF.8)
MT=16,104,105,AND,106,WERE OBTAINED FROM CODE FASCRO (REF.9)
ANGULAR DISTRIBUTION DATA WAS ANALYZED WITH CODE CHAD (REF.10)
THE BINDING ENERGIES AND THRESHOLDS ARE BASED ON REF.11
SHELL AND PAIRING CORRECTIONS WERE TAKEN FROM REF.12
THE NUCLEAR TEMPERATURES IN FILE 5 WERE CALCULATED ACCORDING TO
REF.13
