text: The isotope 254No is especially interesting theoretically as it is in the middle of a series of prolate nuclei from 231Pa to 279Rg, and the formation of its nuclear isomers (of which two are known) is controlled by proton orbitals such as 2f 5/2 which come just above the spherical proton shell; it can be synthesized in the reaction of 208Pb with 48Ca.
