(NAT.KR) REF.2.
FAST NEUTRON CROSS SECTIONS (13.0 KEV. TO 20.0 MEV.)
GENERAL DESCRIPTION
THE TOTAL AND ELASTIC CROSS SECTIONS
CALCULATED WITH ABACUS OPTICAL MODEL CODE(REF.6)
THE INELASTIC, CAPTURE, N,P,
CROSS SECTIONS WERE CALCULATED WITH
CODE CERBERO(REF.7)
MT=16,17,104,105,106 WERE OBTAINED FROM CODE FASCRO
(REF.8)
ANGULAR DISTRIBUTION DATA WAS ANALYZED WITH CODE CHAD(REF.9)
THE BINDING ENERGIES AND THRESHOLDS ARE BASED ON REF.10
SHELL AND PAIRING CORRECTIONS WERE TAKEN FROM REF.11
THE NUCLEAR TEMPERATURES IN FILE 5 WERE CALCULATED ACCORDING TO
REF.12.
