2000So11: identification of 129Pm isotope in 90Zr(197Au,X) reaction at 30 MeV/nucleon; NSCL-MSU A1200 fragment separator used.
2004Xu05: 129Pm isotope was obtained by bombarding a 92Mo target with a 40Ca12+ beam at E=232 MeV. The beam energy at target center could vary from 164-190 MeV. Measured Eγ, γγ(t), (charged particle)γ coin, xγ coin with two coaxial HpGe detectors for γ rays and a HPGe planar detector for x rays.
2008StZX: 58Ni(76Kr,X), E=4.34 MeV/nucleon; measured Eγ, Iγ, γγ-coin using EXOGAM array and SPIRAL facility at GANIL. Four γ rays were assigned to 129Pm in the energy range of 250-680 keV, but no other details are available.
Q-value: Estimated (2012Wa38) uncertainties: 590 for Q(β-), 420 for S(n) and Q(α), 360 for S(p)
Q-value: Q(εp)=6160 300, S(2n)=24240 500, S(2p)=2920 360 (syst,2012Wa38)
