E(level): From least-squares fit to Eγ data
M(γ): Stretched quadrupole from γγ(θ) in 248Cm SF decay, assigned as (E2) in 2015Ko15. Evaluator assigns Q, in the absence of strong supporting data for parity assignment

0.0 | (7/2+) | 1.679 s 15 % β- = 100 % β-n = 22 3 | %β-n is adopted from 2002Sh08 (same value in 2002Pf04 evaluation) based on the least-squares fit of their β-delayed neutron curves. Use of %β-n=17.6 22 recommended by 1993Ru01 (from weighted average of 21.0 11 (1993Ru01), 14 1 (1978Cr03), 22 4 (revision by 1993Ru01 of 19.9 21 in 1977Ru04), 25 4 (revision by 1993Ru01 of 8 in 1968To19)) gave a very poor fit (by a factor of 10 or so) to the decay curve obtained by 2002Sh08 (according to an e-mail reply of April 30, 2002 by the lead author of 2002Sh08). If one excludes the low value of 14 1 in 1978Cr03, the weighted average of other three values quoted by 1993Ru01 is 21.3 11, which is consistent with that obtained by 2002Sh08 and the value adopted by 2002Pf04.

See 2002Pf04, 1993Ru01, 1989BrZI, 1984Ma39, 1982Ru01, 1977Ru10, 1975Iz03 for analysis, reviews and compilations. E(level): πg7/2ν(f7/22) multiplet. This multiplet together with the long half-life of 19/2+ state is consistent with the calculated (1998Bh09) spectrum from shell model. Jπ(level): Probable member of πg7/2ν(f7/22) multiplet. From consistency of experimental and calculated (using shell model) level spectrum for the first five states up to ≈900 keV. It should be pointed out, however, that a 1/2+ state at ≈530 keV predicted by calculations has not been observed. |
