In-beam study of 254No

Shell corrections of superheavy nuclei in self-consistent calculations

“…Beautiful experimental confirmation of large quadrupole deformations in this mass region comes from gammaray spectroscopy. Recent experimental works [26,27] [19,21,28,29]. Still heavier and more neutron-rich elements are expected to be spherical due to the proximity of the neutron shell at N =184.…”

Skyrme mean-field study of rotational bands in transfermium isotopes

“…Predicted quasi-particle spectra are compared with experiment for the heaviest known odd N and odd Z nuclei. Spectra and rotational bands are presented for nuclei around 252,4 No for which experiments are either planned or already running. …”

“…The cross sections to produce deformed transfermium nuclei, which are stabilized by the same shell energy, are larger and studies of fission barrier properties become possible. 254 No is the best candidate for such a study as it has the highest cross section (although still small at around 1 µb) of the heaviest nuclei and the structure of its excited states is quite well known [7][8][9][10][11][12][13][14][15]. A previous attempt at determining the height of its fission barrier yielded a lower limit of ∼ 5 MeV for spins up to 22 [16], which did not allow for differentiating between the available theoretical predictions.…”
