Mass measurements: 2022Si20 (mass excess=-36204 18, δ-tof), 2018Mo14 (M.E.=-36178 73, δ-tof), 2016Me07 (M.E.=-35940 430, tof), 2011Es06 (M.E.=-35280 650, tof)
2022Si20: U(p,X) Cr isotopes were produced with E=480 MeV proton beam impinged on a UCx target at the ISAC facility, TRIUMF. Measured mass using the electrostatic Multiple-Reflection Time-Of-Flight Mass Spectrometer (δ-tof-ms) at TRIUMF’s Ion Trap for Atomic and Nuclear Science (TITAN) facility.
2018Mo14: U(p,X) Cr isotopes were produced with E=1.4 GeV proton on a thick UCx target at the ISOLDE facility, CERN. Measured mass using the δ-TOP mass separator and the ISOLTRAP setup
Source produced by 9Be(86Kr,X), 1992We04
2016Me07: 9Be(82Se,X) U(p,X) E=140 MeV/nucleon 82Se beam from the Coupled Cyclotron Facility at NSCL on a 517 mg/cm2 9Be target. Fragments were separated with the A1900 separator and identified with the S800 spectrograph using time-of-flight. Measured tof spectra. Deduced mass excesses for Cr isotopes.
2011Da08 (also 2002MaZN): Ta(86Kr,X) E=57.8 MeV/nucleon 86Kr beam impinged on 50 mg/cm2 thick tantalum target at GANIL. Measured T1/2.
2011Es06: 9Be(86Kr,X) E=100 MeV/nucleon 86Kr beam at NSCL. Measured tof spectra. Deduced mass excesses.
2005Ga01 (also 2003So21): 58Ni(76Ge,X) E=61.8 MeV/nucleon at GANIL. Fragments were separated by the LISE3 spectrometer. Measured T1/2
2004NiZY: 9Be(86Kr,X) E=63 MeV/nucleon at RIKEN. Measured T1/2
2001So07,1999Le67,1999So20: 58Ni(86Kr,X) E=60.4 MeV/nucleon 86Kr beam at GANIL. Measured T1/2.
1998Am04: Be(86Kr,X) E=500 MeV/nucleon at GSI. Fragments were separated with the FRS separator. Measured T1/2
1992We04: Be(86Kr,X) E=500 MeV/nucleon at GSI. Measured σ. Deduced evidence for existence of 63Cr
1988Zh19: Ti(86Kr,X) E=44 MeV/nucleon at GANIL. Fragments were separated and identified using the (SPEG+α) spectrometer. Deduced evidence for existence of 63Cr
