Q(β-)=3.21×103 keV 4S(n)= 5.81×103 keV 4S(p)= 7.22×103 keV 8Q(α)= -2.7×102 keV 9
Reference: 2012WA38

References:
  A  196Os β- decay (34.9 M) 

General Comments:

No XREF entries are given since all of these levels are observed in the 196Os β- decay (34.9 min).

α proposed g.s. configuration is π(1/2+)(400) + ν(1/2-)(510) Nilsson orbitals. Because of limited experimental data, assignments must be considered tentative.

Cross section and yield measurements: 1976De39, 1977Mo05, 1981Ab02, 1981Pr02.

π- and μ- absorption: 1978De30, 1980Li16, 1981Ha03.

Excitation probability and isomer shift: 1970Ba74.

Gammas: α lack of observation of appreciable ce supports γ-transitions of low multipolarity (1977Ha32).

Q-value: Note: Current evaluation has used the following Q record
