Theory: 1999La23
Produced by 92Mo(58Ni,3p3n), E=325 MeV (1986Wi15). Identification using OASIS mass separator, β-delayed protons in coincidence with Dy K x-rays.
Mass measurement by Penning-trap spectrometer: 2008Ra03 (also 2007Ra37)
Q-value: Note: Current evaluation has used the following Q record -7699 syst 10990 syst -271 16 2860 syst 2003Au03,2008Ra03
Q-value: S(p) from measured masses (2008Ra03). 2003Au03 give 160 360 from systematics
Q-value: ΔQ(β-)=400, ΔS(n)=500 keV, ΔQ(α)=850 keV (2003Au03)
Q-value: Q(εp)=7950 300 (2003Au03)
