General Comments:

1994Se12, 1990Tu01: first identification of 58V from Th(p,F) at E=800 MeV, followed by time-of-flight, isochronous spectrometer, deduced mass.

1994KoZV: 59Co(3He,X) E=11-92 MeV. Measured cross section.

1998Am04: Fragmentation of 86Kr beam with Be target. Measured isotopic half-life.

1998So03: 58V from 9Be(65Cu,X) reaction at 64.5 MeV/nucleon. Measured γ, β, βγ coin, isotopic half-life.

1999So20 (also 1999Le67): 58V from 58Ni(86Kr,X) reaction at 60.4 MeV/nucleon. Measured Eβ, Iβ(t), isotopic half-life.

2001Pr13 (also 2001Pr05): Fragmentation of 70Zn beam with Be target, measured γ, β, βγ coin, isotopic half-life.

2003Ma02: Fragmentation of 86Kr beam with Be target. Measured γ, β, γγ, γβ coin, isotopic half-life.

2005Ga01 (also 2003So21: 58V produced in fragmentation of 76Ge30+ beam on a 58Ni target. LISE3 achromatic spectrometer used to separate fragments; time-of-flight method, energy loss and magnetic rigidity used to identify fragments. Measured Eγ, Iγ, Iβ, γγ, βγ coin, γ(t), lifetimes with four Ge detectors placed around a thick Si telescope. Half-lives determined by fitting procedure involving five parameters: half-lives of mother, daughter and grand-daughter nuclei, the β-efficiency and the background rate over the 1 s collecting time.

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

Q-value: Q(β-n)=4240 250 (2009AuZZ,2003Au03)

Q-value: S(2n)=10270 320 (2009AuZZ); S(2p)=29520 740 (2009AuZZ,syst)

Additional Gamma Comments:

  114  114E(γ): α 114 2 γ seen in 58Ti decay is either a member of γ-cascade from high-lying excited state in 58V or corresponds to direct decay of a 114 level to the g.s. Since no other transition was observed, the latter possibility seems more likely. Other: 116 2 (2002MaZN)
