61MN c 2009Cr02:{+61}Cr produced through the {+9}Be({+76}Ge,X) reaction at a
61MN2c beam energy of 130 MeV/nucleon. The {+76}Ge beam was produced by the
61MN3c coupled cyclotrons at the National Superconducting Cyclotron
61MN4c Laboratory at Michigan State University. Fragments were separated
61MN5c using the A1900 fragment separator. The |b and |g spectra were measured
61MN6c using the Beta Counting System and the Segmented Germanium Array, as
61MN7c well as three Si PIN detectors. Measured E|g, I|g, |g|g, |b, |b|g
61MN8c coin, (fragment)|b coin, half-life of the {+61}Cr ground state.
61MN c Others dealing with production and half-life of {+61}Cr:
61MN c 2001So07 (also 1999So20 and 1999Le67): {+61}Cr produced in the
61MN2c fragmentation of 60.4 MeV/nucleon {+86}Kr beam with {+58}Ni target;
61MN3c LISE3 spectrometer at GANIL facility. Measured half-live of {+61}Cr.
61MN c 1998Am04: {+61}Cr formed in fragmentation of 500 MeV/nucleon {+86}Kr
61MN2c beam incident on a Be target, FRS spectrometer at GSI facility.
61MN3c Measured half-life of decay of {+61}Cr.
61MN c In view of the large Q value of 9.4 MeV, this decay scheme may be
61MN2c incomplete since the levels, currently, are reported only up to 2.4 MeV
61MN c From RADLIST code, deduced total decay energy of 9290 {I450} keV
61MN2c agrees with 9290 {I130} expected from Q value
61MN cB IB,LOGFT$Apparent |b feedings and log| {Ift} values deduced by
61MN2cB 2009Cr02 from absolute |g-ray intensities. Uncertainties in log| {Ift}
61MN3cB values are given by 2009Cr02 as 0.1 to 0.2, but the evaluators omit
61MN4cB these here since the decay scheme is most likely incomplete and
61MN5cB the log| {Ift} values can be treated as (lower) limits only
