E(level): From least-squares fit to Eγ’s
Jπ(level): Arguments for the assignments to the g.s. and first two excited levels are based on shell-model considerations, systematics of s1/2+, d3/2+ and h11/2- levels, systematics of M4 transitions and atomic-beam measurements of spins in adjacent nuclei. For levels from 956 to 2063 keV inclusive, Jπ’s are taken from 1982No08, based on log ft values or γ’s from (to) levels with assigned Jπ’s, in analogy with 145Gd isotone levels. Above 2063 keV the Jπ values are from 1985Br07, who rely on shell-model considerations and low-energy γ mults. Because the Jπ’s of the g.s.’s of both 147Ho parent and 147Dy are tentative, all the other assignments are tentative (evaluator)
