Q(β-)=4778 keV 201S(n)= 5827 keV 201S(p)= 12959 keV 479Q(α)= -3812 keV 210
S(2n)= 10276 keV 201S(2p)= 23658 keV 479
Reference: 2017WA10

General Comments:

Assignment: 235U(n,F), ion chem, ms; detection of Pr K| x ray (1990Ta07).

All excited state data are from 252Cf SF decay

The 3.1-S activity previously assigned to 152Ce by 1983Hi05 is now believed to belong to 152Pr (1988Ka14)

Levels: Calculations:

Levels: Emission of 20O from 152Ce (1996Ku05)

Levels: Equilibrium shape (1984Na22)
