General Comments:

Other reactions and nuclear structure theory: 2009Sa25, 2008Do12, 2005Pa73, 1998Sa08.

Fission barrier as a function of deformation was calculated in 1985Cw01.

Activity produced by the 208Pb(40Ar,3n) reaction with a cross-section of 15 nb 5. 245Fm was separated using the gas-filled recoil ion separator GARIS. Measured Eα=8.15 MeV (2007Ha29). Other value: Eα=8.15 Mev 2 (1967Nu01).

Q-value: Note: Current evaluation has used the following Q record

Only α decay was observed. Gross β calculations of 1973Ta30 yield T1/2(ε+β+ decay)≈100 sec, which corresponds to %ε+%β+≈4.2.
E(level): Only α decay was observed. Gross β calculations of 1973Ta30 yield T1/2(ε+β+ decay)≈100 sec, which corresponds to %ε+%β+≈4.2.
