General Comments:

Production: 144Sm(51V,3n), E=230 1 MeV (mid-target); 96.47% 144Sm target; recoils separated in flight by SHIP velocity filter then implanted into 16-strip Si position-sensitive detector; tof veto of beam particles; four-fold segmented Clover Ge detector; measured Eα (FWHM≈25 keV or 45-75 keV), Iα, Iγ, recoil-γ coin, recoil-α-γ coin (particle-γ Δt|<5 μs) (2006An04; see also 2005AnZY). Other: 2003Ke08.

Identification: observed α decays are correlated with known α decays from 188Bi daughter isomers (2006An04).

Theory:

Calculations using Coulomb and proximity potential model: T1/2, and HF for α decay from g.s. and isomer (2011Sa10).

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

T1/2(level): From α(t) (2006An04).
