ORIGINAL COMMENT IS:
RCN-4 EVALUATION H.GRUPPELAAR AND H.A.J. VAN DER KAMP RU101H 05
MINIMUM ENERGY .00001 EV
MIN EN OF STATISTICAL MODEL 1.04426 KEV
ENERGY OF FIRST EXCITED STATE .12720 MEV
CONTINUOUS STAT MODEL ABOVE .68500 MEV
HIGH ENERGY MODEL ABOVE 6.50000 MEV
MAXIMUM ENERGY 20.00000 MEV
LEVEL DENSITY PARAMETER RU101 16.99000 1/MEV
LEVEL DENSITY PARAMETER RU100 14.50000 1/MEV
*****RCN-4 EVALUATION MARCH 1985 ********************************
*****ADJUSTED TO STEK AND PHENIX INTEGRAL DATA********************
*****RU-101*******************************************************
RESOLVED RESONANCE ENERGY RANGE UPTO 1035 EV
THERMAL ABSORPTION CROSS SECTION=3.4+-0.9 BARN(MU81)
RESONANCE INTEGRAL=100+-20 BARN(MU81)
CALCULATED VALUE THERMAL ABSORPTION CROSS SECTION=3.456 BARN
CALCULATED VALUE RESONANCE INTEGRAL=112.7 BARN
EVALUATION WITH CODE SIGMA-ECN AT 0 K, MULTILEVEL FORMULA
RESOLVED RESONANCE PARAMETERS UPTO 1035 EV WERE TAKEN FROM
THE BROOKHAVEN COMPILATION(MU81)
RANDOM SPIN VALUES HAVE BEEN ADDED TO THE RESONANCES FOR
WHICH NO SPINS WERE MEASURED
ALL RESONANCES HAVE BEEN ASSUMED TO BE S-WAVE RESONANCES
NO HYPOTHETICAL NEGATIVE RESONANCE WAS NEEDED IN THIS CASE
STRENGTH FUNCTION REGION UPTO 127.2 KEV
ALL CROSS SECTIONS WITH CODE SASSI-ECN
S-WAVE STRENGTH FUNCTION= 0.59+-0.04(MA80B)
P-WAVE STRENGTH FUNCTION= 6.1+-0.4(MA80B)
OTHER STRENGTH FUNCTIONS FROM OPTICAL MODEL
DOBS=18.5 EV, THIS VALUE HAS BEEN ADJUSTED TO FIT THE
STEK AND PHENIX INTEGRAL DATA
S-WAVE CAPTURE WIDTH= 180+-15 MILLI ELECTRONVOLT(MU81)
CALCULATED P-WAVE CAPTURE WIDTH= 190 MILLI ELECTRONVOLT
THE CALCULATED CAPTURE CROSS SECTION IS SOMEWHAT BELOW THE
DATA OF MACKLIN ET AL(MA80B),BUT STILL WITHIN ERROR MARGINS.
HIGH ENERGY REGION ABOVE 127.2 KEV
THE CROSS SECTIONS HAVE BEEN CALCULATED WITH A COMBINATION
OF THE STATISTICAL-MODEL CODE SASSI-ECN AND THE PRECOMPOUND-
MODEL CODE PRANG. THE DISTRIBUTIONS OF THE OUTGOING NEUTRON
ENERGIES ARE STILL BASED UPON THE EVAPORATION MODEL
OPTICAL MODEL FROM EVALUATION OF AUTHORS
LEVEL SCHEME FROM NUCLEAR DATA SHEETS(HA79A)
SQUARED TARGET SPIN CUT-OFF FACTOR=7.1 FROM EXPERIMENTAL
LEVEL SCHEME
