  A  237Cm α decay 

General Comments:

1957Th10: production and identification of 233Pu in 233U(α,4n), E=46 MeV, followed by chemical separation.

In 237Np(6Li,6n) reaction followed by mass separation of fragments, 2002As08 assign an α group at 6660 10 to the decay of 237Cm that may feed the g.s. of 233Pu, but the half-life of 237Cm is not determined due to low statistics. evaluators consider this assignment as preliminary

Theoretical studies: consult the NSR database at for 11 references dealing with theoretical calculations about decay modes and half-lives, and four for nuclear structure.

Q-value: Estimated ΔQ(β-)=ΔS(p)=110 (2017Wa10)

Q-value: S(2n)=14400 60, S(2p)=8330 50 (2017Wa10)
