General Comments:

1999Xu05 (also 2005Xu04): 129Sm produced in 96Ru(36Ar,3n) reaction at E(36Ar)=165 MeV at NLHIAL, China. Helium-jet transport system. Measured pγ coin, half-life using silicon and HPGe detectors. Statistical model calculations

Q-value: Estimated (2012Wa38) uncertainties: 710 for S(n), 590 for S(p), 640 for Q(α) (2012Wa38)

Q-value: S(2p)=1180 590, Q(εp)=10880 540 (syst,2012Wa38). S(2n)=25290 (1997Mo25,theory)
