High-precision Penning trap mass measurements of neutron-rich chlorine isotopes at the N=28 shell closure
H. Erington, G. Bollen, G. Dykstra +9
Although it is known that the spherical shell closure erodes, the strength of the closure with decreasing proton number is an open question in nuclear structure. In t…
