General Comments:

1988Bo06, 1985Bo49: 58Cr produced and identified in W(76Ge,X) reaction at 11.5 MeV/nucleon followed by mass separation at GSI facility. Measured γ, β, βγ coin, isotopic half-life using Ge and Si detectors and plastic scintillators

1994Se12, 1990Tu01: 58Cr produced in Th(p,X) at E=800 MeV, followed by mass separation and time-of-flight isochronous spectrometer, deduced mass

1996Do23: 58Cr produced in Be(65Cu,X) at E=64.5 MeV/nucleon at GANIL facility.

Structure calculation (levels, transition probabilities, etc.): 2008Ka41, 2002Ca48

The β-n decay of 59V to 58Cr has been investigated by 2005Li53 and an upper limit of 3% feeding of the first 2+ state in 58Cr has been suggested

Q-value: Note: Current evaluation has used the following Q record

Q-value: S(2n)=12700 200, S(2p)=27480 280 (2009AuZZ)
