GENERAL DESCRIPTION
TOTAL AND ELASTIC CROSS SECTIONS CALCULATED WITH ABACUS OPTICAL
MODEL CODE (REF.5)
THE INELASTIC, CAPTURE, N,P AND N-4HE CROSS SECTIONS WERE
CALCULATED WITH CODE CERBERO (REF.6)
MT=16,104,105,106 WERE OBTAINED FROM CODE FASCRO (REF.7)
ANGULAR DISTRIBUTION DATA WAS ANALYZED WITH CODE CHAD (REF.8)
THE BINDING ENERGIES AND THRESHOLDS ARE BASED ON (REF.9)
SHELL AND PAIRING CORRECTIONS WERE TAKEN FROM REF.10
THE NUCLEAR TEMPERATURES IN FILE 5 WERE CALCULATED ACCORDING TO
REF.11
