High-precision mass measurements of nickel, copper, and gallium isotopes and the purported shell closure at N = 40
ATOMIC MASSES 57,60,64,65,66,67,68,69Ni, 65,66,67,68,69,70,71,72,73,74,76Cu, 63,64,65,68,69,70,71,72,73,74,75,76,77,78Ga; measured masses; analyzed the resulting mass surface for signs of magicity, compared the behavior of N=40 with that of the known magic numbers and with midshell behavior.
NUCLEAR STRUCTURE Z=28, 29, 31; analyzed two-neutron separation energies, pairing energies, masses, compared with mass models, found no evidence for shell closure at N=40.
