Q(β-)=-3.1×103 keV SYS(n)= 7.2×103 keV SYS(p)= 2.3×103 keV SYQ(α)= 7.2×103 keV SY
Reference: 2012WA38

General Comments:

232Am produced in the 230Th(10B,8N) reaction. Measured excitation function, detected fission fragments (1967Ku15).

232Am produced in the 237Np(α,9N) reaction (Eα=104 MeV). Detected fission fragments and α particles from the 238Np decay chain (1978Ha05).

232Am produced in the 237Np(α,9N) reaction (Eα=94-98 MeV). Americium was chemically separated. Measured K x-rays and electron-capture delayed fission fragments (1990Ha28).

Q-value: Note: Current evaluation has used the following Q record 7110 SY2180 SY7270 syst 2003Au03

Fission fragments following the electron-capture (ε) decay of 232Am have been detected. An emission probability of 0.069% 10 has been estimated on the basis of a measured K x-ray/fission ratio and reported in 1990Ha28. The detected fission fragments probably originate from highly excited states in 232Pu populated in the ε decay of 232Am.
