Quenching of the N=32 neutron shell closure studied via precision mass measurements of neutron-rich vanadium isotopes

“…4 the new vanadium mass excesses determined from our direct mass measurements are compared to the averages reported in the AME2016 [25]. The previous measurements relying upon nuclear reactions [17][18][19][20] and decay measurements [21][22][23][24] are confirmed by our direct mass measurements of A = 52 − 55 V isotopes. For 54 V we were able to reach a comparable uncertainty and for FIG.…”

“…By contrast, in 24 Cr [16] and 23 V no shell effects can be seen at N = 32. Despite intense work in this region of the nuclear chart, the masses of neutron-rich 23 V isotopes remain the only mass values around N = 32 purely based on indirect techniques (nuclear reactions [17][18][19][20] and decay measurements [21][22][23][24]) within the AME2016 [25].…”
