General Comments:

Other reactions:

191Ir(n,8nγ), 0.2 MeV<E(n)<300 MeV (2005FoZZ): observed 96.8γ.

184W(7Li,X), E=70 MeV (2005Cl07); observed five transitions.

For hfs and isotope shift data see, for example, 1996Se15.

See 1988Be16 for comparison of levels populated in ε decay with level structure predicted from two-quasiparticle plus rotor model calculations.

Q-value: Note: Current evaluation has used the following Q record -2280 30 7480 40 3240 60 3802 35 2003Au03,2009AuZZ
