EEC, IE from 150SM2C 1962Bi16, 1963Gr18, 1966El05 and 1967Pr08. 150SM C 1966Sm03: investigated the G rays resulting from thermal-neutron 150SM2C capture in 149SM with a bent-crystal spectrometer 150SM3C in the energy range of 40 KEV to 150SM4C 2.4 MEV. The source consisted of 350 MG of SM oxide enriched 150SM5C to 83% in 149SM. This sample absorbed AP 100% of the 150SM6C thermal neutron flux initially but as the 149SM (SIGMA=64000 barns) 150SM7C was converted to 150SM, the neutron transmission 150SM8C increased. A study of this effect allowed the 150SM9C calculation of intensity in units of photons per 100 150SMAC neutron captures. G rays in 150SM, 151SM, and 152SM were 150SMBC identified by comparing plots of intensity versus 150SMCC integrated neutron flux. In this manner 217 G rays were 150SMDC identified with thermal neutron capture in 149SM. Quoted 150SMEC energies and intensities were obtained from averages of 5 to 10 150SMFC independent determinations. Errors are probable errors reflecting 150SMGC a 60% confidence limit and include both a statistical uncertainty 150SMHC and an estimated systematic error. The bent crystal G-ray data 150SMIC were combined by the authors with the conversion-electron 150SMJC data of 1962Bi16 and 1963Gr18 to obtain K-conversion coefficients. 150SMKC GG coincidence and angular-correlation data were taken. A 150SMLC decay scheme was proposed by 1966Sm03 based up to the 1642-KEV 150SMMC level on the G-ray work of that author and the calculated 150SMNC K-conversion coefficients. The decay scheme is extended up to 150SMOC 2020 KEV by comparison with the work of 1965Gu03, 1964Ke03 and 150SMPC 1963Gr18. 150SM C 1963Gr18: studied the primary and secondary gammas in the 150SM2C G-ray spectrum emitted in neutron capture in 149SM. 150SM3C Assuming that all G rays with 150SM4C EG>(SN-2) MEV are primary transitions in 150SM, authors obtain 150SM5C SN=7983 KEV 4, to be compared with 7985.5 KEV 7 (1985Wa02). 150SMDC Primary G rays listed below are taken from this source. 150SM C 1969Re11: studied the directional anisotropy of capture G rays 150SM2C from aligned 149SM nuclei. JPI were assigned by combining these 150SM3C data with ECC data. 150SM CL E Listed energies are least-squares-fitted values with input 150SM2CL from all photon transitions between levels while holding the energy 150SM3CL of the capturing state constant. SN is from 1985Wa02. 150SM CL Levels below 3 MEV are from 1966Sm03, unless otherwise noted. 150SM2CL Levels above 3 MEV are those seen by 1964Ke03 in 150SM3CL the (D,P) reaction to which primary G rays may be assigned 150SM4CL from the (N,G) E=thermal results of 1963Gr18. 150SM CL J From adopted levels except as noted. 150SM CG G rays below 2350 KEV are from 1966Sm03, unless otherwise 150SM2CG noted. G rays above 2350 KEV are taken from 1963Gr18. 150SMDCG From 1764.77-KEV level and up, some G rays seen by 1966Sm03 have 150SMDCG been placed in the decay scheme by the evaluator on the basis of 150SMDCG energy fit. 150SM CG The G rays placed from level 7986 are a partial list of those 150SM2CG reported in the literature and consist of transitions reported by both 150SM3CG 1963Gr18 and 1969Ra10. Above 5616 KEV G rays reported by both 1963Gr18 150SM4CG and 1969Re04 are listed. EG have been taken from 1963Gr18 and IG from 150SM5CG 1969Ra10 or 1969Re04. The multipolarities are deduced from EKC based 150SM6CG on IG of 1969Ra10 or 1969Re04 and icek data of 1966El05 or 1970Pa20. 150SM7CG 1969Re11 also give multipolarities based on ECC of 1966El05 but 150SM8CG reanalyed. The chosen multipolarities are consistent with both sources. 150SM CG M Based on GG(THETA) 150SM2CG and KC data by 1966Sm03, normalized to the assumption that the 150SM3CG 333.94-KEV G ray is a pure E2 transition (see general comment in level 150SM4CG listing). Above 5 MEV, multipolarities are from 1969Re11 150SM5CG on basis of capture G-ray anisotropy and/or CC's calc from data 150SM6CG of 1966El05 and 1963Gr18. 150SM CL J(A) Confirmed by 1969Re11.
