Q(β-)=4163 keV 12S(n)= 6550 keV 15S(p)= 9222 keV 17Q(α)= -2526 keV 16
Reference: 2017WA10

References:
  A  151Ce β- decay (1.76 S)  B  151Ce β- decay (1.02 S):?
  C  252Cf SF decay 

General Comments:

Mass separated fission product from spontaneous fission of 252Cf. Atomic number identified but mass number less secure. See 151Ce ’adopted levels’. 1987MaZY identify 151Pr from mass separated fission fragment

Mass measurement (Penning-trap method): 2006Sa56 (also 2004Cl07)

Q-value: S(2n)=11883 15, S(2p)=21140 17
