General Comments:

162Ta produced and identified by 1985Li14 in 175Lu(3He,xn), E=280 MeV reaction; measured half-life. In 1984Sc06, α decay of 166Re was studied which indirectly implied the formation of daughter nuclide of 162Ta.

Q-value: S(2n)=20100 80, S(2p)=4090 90, Q(εp)=5490 70 (2021Wa16)

E(level): From least-squares fit to Eγ data. Uncertainties for some of the gamma rays as indicated were doubled by the evaluator to get an acceptable fit

Jπ(level): Based on tentative assignment of 9- for the bandhead, and comparison with high-spin structure of 164Ta (2011Gh08). Thus all Jπ assignments are considered here as tentative

M(γ): Assignment by the evaluator from DCO values; in addition, (E2) assigned for two low-energy ΔJ=2, quadrupole transitions from RUL, assuming level half-life less than 20 ns or so from coincidence resolving time. In other cases, where DCO values are given by 2011Gh08, it was not possible to make secure assignments since the values overlap for ΔJ=2, quadrupole and ΔJ=1, dipole transitions
