162TB C 162GD has been produced by double-neutron capture in enriched 160GD
162TB2C with radiochemistry (1967Wa05,1970Ch02) and from spontaneous fission
162TB3C of 252CF with radiochemistry (1982Ge07). Measurements include
162TB4C G singles and GG, GX, and GB coincidences.
162TB CL Decay scheme is from 1982Ge07, and is similar to those of
162TB2CL 1970Ch02 and 1967Wa05.
162TB CL The consistency of the scheme is supported
162TB2CL by the fact that the sum of the energies of the radiations is
162TB3CL 1395 keV 56 which agrees with the Q value of 1400 100.
162TB CG Data are from 1982Ge07, unless otherwise noted. Others:
162TB2CG 1970Ch02, 1967Wa05.
162TB CB E From 1970Ch02.
162TB CB IB From evaluators' assumption that 100% of the decays
162TB2CB depopulate the levels at 341 and 442 keV (that is, no B-
162TB3CB feeding of the ground state and 39 level) and no G feeding of
162TB4CB the 341-keV level. From LOGFT GE 5.9 for 0+ to 1- ground state
162TB5CB (1973Ra10), IB-(0) LE 13% and from LOGF1T GE 8.5 for 0+ to 2- at
162TB6CB 39 keV (1973Ra10), IB-(39) LE 0.15%.
162TB CL E From least-squares fit to G energies.
162TB CL J From 162TB Adopted Levels. Rotational band and Nilsson
162TB2CL configuration assignments are given there.
162TB D Experimental methods:
162TB D 1967Wa05: 162GD from double-neutron capture in enriched (94%) 160GD
162TB2D with radiochemistry. G's measured with NAI(TL) detectors.
162TB D 1970Ch02: 162GD from double-neutron capture in enriched (94.8%) 160GD
162TB2D with radiochemistry. G's measured with Ge and Si(Li) detectors
162TB3D and B's with Si(Li) detector. GX and GB coincidences measured.
162TB D 1982Ge07: 162GD from 252CF spontaneous fission with radiochemistry.
162TB2D G's measured with Ge detector.

162TB CN NR Based on evaluators' assumption that 100% of the decays
162TB2CN depopulate the levels at 341 and 442 keV. From LOGFT
162TB#CN arguments, the direct B- feeding of the ground state should
162TB$CN be LE 13%. If IB-(0) were this large, the normalization factor
162TB%CN would be reduced from 0.51 to 0.44. Normalization to
162TB3CN 100% feeding of the ground state is not useful since RI(39) has
162TB4CN a large (20%) uncertainty and the E2 mixture in this G would
162TB5CN have to be determined from the intensity balance at the 39 level
162TB6CN in any case. 1982Ge07 report a normalization factor of 0.61 6
162TB7CN based on a value of 43 1 G's per 100 decays for the 807-keV G
162TB8CN in the B- decay of 162TB; but this results in a total B-
162TB9CN intensity of 118 12 per 100 decays of 162GD. [Result reported
162TB0CN by 1982Ge07 is RI(442G from 162GD decay)/RI(807 G from
162TBACN 162TB decay)=1.43 2]

162GD DP T From 162GD Adopted Levels and is based on
162GD2DP 8.2 M 3 (1970Ch02) and 8.55 M 28 (1982Ge07).

162TB CG E Average of 39.1 2 (1982Ge07) and 38.8 2 (1970Ch02).
162TB CG RI Average of 9 2 (1982Ge07) and 14 3 (1970Ch02).
162TB CG M,CC CC value deduced by evaluators from intensity balance at 39
162TB2CG level for current decay scheme; added G's feeding 39 level will
162TB3CG increase CC value. From CC(M1)=5.58 and CC(E2)=135, G is
162TB4CG primarily M1 with some E2 probable. Measured x/G intensity
162TB5CG ratio and L x-ray energy are consistent with this (1970Ch02).
