General Comments:

Q(β-n)=3660 600 (syst 1993Au05)

Isotope produced and identified in mass-separated fission products from 235U(n,F) (1991Kr15,1990Wi12,1987Ar21,1987LuZX)

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

Q-value: Uncertainties are 610 for Q(β-), 780 for S(n), 1000 for S(p)

-n is quoted by 1993Ru01 from Reeder et al. in Proceedings of the Specialists Meeting on Delayed Neutron Properties, p37 (1986).
  0.0+Y 1.27 s 30 
% β- = 100
Delayed neutron decay is possible from this isomer also but agreement of T1/2 from 698γ(t) (1990Wi12) and from β-n(t) (1991Kr15, 1993Ru01) suggests that most of the delayed neutrons are from the state with lower T1/2.
