β-delayed fission of ²³⁰Am

RADIOACTIVITY ²³⁰Am(β⁺F)[from ²⁰⁷Pb(²⁷Al, 4n), E=145 MeV]; measured fission fragments, double-fold fission fragment coincidences, total energy spectrum, α-α correlations using the GARIS recoil-ion separator at RIKEN. Analyzed TKE(²³⁰Pu); deduced T_1/2 for ²³⁰Am, lower limit of β-delayed fission probability of ²³⁰Am. Systematics of β⁺-delayed fission probabilities for ^230,232,234Am, ^{240,242,244,246,248}Es, ^236,238,240Bk nuclei. ²³⁰Am found to have the highest lower limit for β⁺-delayed fission probability so far among all the known nuclei decaying by this mode.
