E(level)	J^π(level)	T_1/2(level)	Comments
0.0	(4+)	3.57 s 18 % β^- = 100	J^π(level): From Δπ=no for the 98 and 115γ’s, π must be the same for the g.s., 115, and 212 levels. For the g.s., the probable Nilsson states suggest configurations π3/2[541]~#ν3/2[521] or π3/2[541]~#ν5/2[642] (2011Li41) giving K^π=3⁺ and 4-, respectively. For J(g.s.)=4, mult(115γ) gives J^π(115 level)\|>3 so there will be no direct β^- feeding. from the β^- decay scheme of 1995Ya21 one can deduce a β^- feeding to the 212 level of≈45% and thus a log ft of 4.6. since the decay scheme is incomplete, this feeding is likely an overestimate, but even if it were a factor of 10 smaller, the log ft would still be consistent only with J^π(212 level)=1⁺. Then, from the mults as given above, it follows that Jπ(115 level)=3⁺ and π=+ for the g.s. For J(g.s.)=3, no available Nilsson configuration would give 3-. For Jπ(g.s.)=3⁺, the above restriction on mult(115γ) is removed allowing E2 and thus allowing Jπ(115)=1⁺ and the possibility of a direct β^- branch to this level. In this case, the combined feeding to the 115 and 212 levels is still large, giving a low log ft and thus requiring Jπ=1⁺ for one or both of the 115 and 212 levels. 2011Li41 suggest that for the Kπ=3⁺ configuration, the J=4 member is expected to lie below the J=3 member. From all the above arguments, the most probable Jπ assignment for the g.s. is 4⁺, with configuration π3/2[541]~#ν3/2[521]. One then has probable Jπ=3⁺ and 1⁺ for the 115 and 212 levels, respectively, and an M1 component for the 98γ is ruled out.
