General Comments:

Production: 144Sm(46Ti,3n), E=224 1 MeV; 96.47% 144Sm enriched target; recoils separated in flight by SHIP velocity filter then implanted into 16-strip Si position-sensitive detector; Time-of-flight veto of beam particles; four-fold segmented Clover Ge detector; measured Eα, Iα, Iγ, recoil-γ coin, recoil-α-γ coin (particle-γ ΔT1/2|<5 μs) (2006An11; see also 2007An19).

Identification: observed 7528α is in prompt coincidence with 286γ in 183Pb and correlated with both known α decays from the g.s. of the 183Pb daughter and also with the known α decays from 179Hg and 175Pt.

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

Jπ(level) T1/2(level)
  0.0 (1/2-,5/2-) 1.40 ms 25 
% α ≈ 100

T1/2(level): From α(t) (2006An11).
