摘要

We present mass excesses (ME) of neutron-rich isotopes of Ar through Fe, obtained via time of flight B rho mass spectrometry at the National Superconducting Cyclotron Laboratory. Our new results have significantly reduced systematic uncertainties relative to a prior analysis, enabling the first determination of ME for Ti-58,Ti-59, V-62, Cr-65, Mn-67,Mn-68, and Fe-69,Fe-70. Our results show the N = 34 subshell weaken at Sc and vanish at Ti, along with the absence of an N = 40 subshell at Mn. This leads to a cooler accreted neutron star crust, highlighting the connection between the structure of nuclei and neutron stars.
