64MN c 2012Ka36: {+64}Mn isomer produced in {+9}Be({+238}U,F) reaction
64MN2c with E({+238}U)=345 MeV/nucleon provided by the RIBF accelerator
64MN3c complex at RIKEN facility. Fission fragments were separated and
64MN4c analyzed by BigRIPS separator, transported to focal plane of
64MN5c ZeroDegree spectrometer and finally implanted in an aluminum stopper.
64MN6c Particle identification was achieved by |DE-tof-B|r method.
64MN7c Delayed gamma rays from microsecond isomers were detected by three
64MN8c clover-type HPGe detectors. Measured E|g, I|g, |g|g-coin, isomer
64MN9c half-life. Number of implanted fragments=1.6|*10{+5}
64MN c 2011Li50: {+64}Mn isotope produced in the fragmentation of
64MN2c 140 MeV/nucleon {+76}Ge beam with {+9}Be target. Fragments separated
64MN3c using A1900 Fragment separator at NSCL-MSU and identified by
64MN4c time-of-flight and energy loss. Delayed |g rays were detected using
64MN5c the SeGA array of 16 detectors. Measured E|g, I|g, |g|g-coin, and
64MN6c half-life of the isomer
64MN c 2005GaZR: {+64}Mn produced in fragmentation of {+76}Ge{+30+} beam on a
64MN2c {+58}Ni target. The LISE3 achromatic spectrometer used to separate
64MN3c fragments. Transmitted nuclei were identified by three consecutive Si
64MN4c detectors where two served for energy loss and time-of-flight
64MN5c measurements while the last determined their residual energies.
64MN6c Measured E(ce), ({+64}Mn fragment)(ce)(t), |g(ce) coin, Si and Ge
64MN7c (Clover) detectors.
