Constraining the trend of the N=50 shell gap towards 100Sn with the masses of 96−98Cd
This paper presents precise mass measurements of neutron-deficient 96−98Cd isotopes using ISOLTRAP at CERN to determine the N=50 shell gap at Z=48 and constrain the mass surface near 100Sn, revealing an enhancement of the shell gap towards the doubly magic nucleus that challenges state-of-the-art theoretical models.
