50 TO 200 KEV : BASED ON THE MEASURED DATA OF GARG ET
AL./5/ BELOW 100 KEV AND OF WHALEN ET
AL./6/ BETWEEN 100 AND 200 KEV. THE

/9/
THE OPTICAL POTENTIAL PARAMETERS USED ARE AS FOLLOWS /10/ (IN
THE UNITS OF MEV AND FM):
V = 51.725 - 0.447*E R0 = 1.221 A0 = 0.683
WS = 8.44 + 0.055*E RS = 1.223 AS = 0.507

MT=4,51-87,91 INELASTIC SCATTERING
STATISTICAL MODEL CALCULATIONS WERE MADE WITH CASTHY/9/
BELOW 3 MEV BY TAKING ACCOUNT OF COMPETING PROCESSES,
AND WITH GNASH/11/ ABOVE 3 MEV INCLUDING PREEQUILIBRIUM
EFFCETS. THE DIRECT PROCESS COMPONENTS WERE CONSIDERED
FOR 10 DISCRETE LEVELS.
