Abstract :
An 879.9(2) keV γ-ray transition has been identified following the β decay of 58V and assigned as the 2+1→0+1 transition in 58Cr34. A peak in the energies of the first excited 2+ states for the even–even chromium isotopes is now evident at 56Cr32, providing empirical evidence for a significant subshell gap at N=32. The appearance of this neutron subshell closure for neutron-rich nuclides may be attributed to the diminished π1f7/2–ν1f5/2 monopole proton–neutron interaction as protons are removed from the 1f7/2 single-particle orbital.
