They are 4092 1451 33 based on the measured data by Boldeman et al./76Bo/. 4092 1451 34 Parameters of a negative resonance and effective scattering 4092 1451 35 radius were adopted from the recommendation of Mughabghab 4092 1451 36 et al./81Mu/. 4092 1451 37 Unresolved resonance region : 60 keV - 200 keV. 4092 1451 38 The neutron strength functions S0 and S1, as well as 4092 1451 39 the radiative widths Gg(s) and Gg(p) are estimated from 4092 1451 40 the resolved resonance parameters, and S2 was calculated with 4092 1451 41 the optical model. The observed level spacing was determined 4092 1451 42 to reproduce the capture cross section calculated with GNASH. 4092 1451 43 The effective scattering radius was obtained from fitting 4092 1451 44 to the calculated total cross section at 70 keV. 4092 1451 45 4092 1451 46 Typical values of the parameters at 70 keV: 4092 1451 47 S0 = 0.750e-4, S1 = 7.200e-4, S2 = 0.880e-4, 4092 1451 48 Gg(s)= 0.196 eV, Gg(p)= 0.244 eV, R = 6.680fm. 4092 1451 49 4092 1451 50 Calculated cross sections for 2200 m/s (barn): 4092 1451 51 total = 5.074, elastic = 4.855, capture = 0.219 4092 1451 52 Capture resonance iintegral above 0.5 ev : = 0.634 barn 4092 1451 53 4092 1451 54 MF = 3 Neutron cross sections: 4092 1451 55 Neutron cross sections in the energy range 0.02-20 MeV were 4092 1451 56 calculated by the GNASH code /96Yo/ modified to take into 4092 1451 57 account neutron width fluctuation, using aphrouch /90Ho/. 4092 1451 58 Neutron transmission coefficients were calculated within 4092 1451 59 the coupled-channel model (code ECIS /70Ra/) for the optical 4092 1451 60 potential /80Ar/, imaginary part of which was modified to take 4092 1451 61 into account the direct excitation of the low laying 2+ and 4092 1451 62 3- levels. 4092 1451 63 Resulting potential parameters are the following: 4092 1451 64 Well depth(MeV) Energy range(MeV) Giometry(fm) 4092 1451 65 Vr=49.0-0.28E 0
