1985Gu14: first evidence for production of 62Cr in Ti,Ta(86Kr,X) at E=33 MeV/nucleon; energy loss and time-of-flight methods.
1990Tu01, 1994Se12: mass measurements by time-of-flight method; Th(p,F) production method
1998Am04: 62Cr produced in fragmentation of 86Kr beam at 500 MeV/nucleon hitting a Be target at GSI facility. First measurement of isotopic half-life.
1999So20 (also 1999Le67): 62Cr produced in 58Ni(86Kr,X), E=60.4 MeV/nucleon at GANIL facility using LISE3 doubly achromatic spectrometer. Measured Eγ, Iγ, βγ coin, isotopic half-life from β decay timing.
