β-delayed neutron emission of ⁶⁴Mn, ⁶²Cr, and ⁶⁵Fe

RADIOACTIVITY ⁶⁴Mn(β^-), (β^-n) [from ⁹Be(⁸²Se, X), E=140 MeV/ nucleon]; measured decay products, Eγ, Iγ, En, In; deduced T_1/2, neutron emission probability. ⁶²Cr(β^-)[from ⁹Be(⁸²Se, X), E=140 MeV/nucleon];⁶²Mn(β^-)[from ⁶²Cr(β^-)⁶²Cr(β^-)]; deduced T_1/2. ⁶⁵Fe(β^-), (β^-n) [from ⁹Be(⁸²Se, X), E=140 MeV/ nucleon]; deduced upper limit for neutron emission probability. No population of long-lived isomer in ⁵²Mn detected, as well neutron emission from ⁵²Mn. Stack of 2 Si PIN detectors, summing NaI detector (SuN) and Beta Counting Station (BCS) housed in the bore of the Neutron Emission Ratio Observer (NERO) neutron long counter system at the NSCL.
