Times Cited Count:1 Percentile:42.67(Chemistry, Inorganic & Nuclear)Fission barrier height and its angular-momentum dependence have been measured for the first time in the nucleus with the atomic number greater than 100. The entry distribution method, which can determine the excitation energy at which fission starts to dominate the decay process, was applied to No. The fission barrier of
No was found to be 6.6 MeV at zero spin, indicating that the
No is strongly stabilized by the nuclear shell effects.

Times Cited Count:34 Percentile:82.19(Physics, Multidisciplinary)Fission barrier heights of a shell-stabilized superheavy nucleus No have been determined as a function of spin up to 19
through the measured distribution of entry points of
deexcitations in the excitation energy vs. spin plane. The fission barrier height of
No was determined to be 6.0 MeV at spin 15
, and 6.6 MeV at spin 0
by extrapolation. This demonstrates that the shell effect actually enlarges the fission barrier in such heavy nuclei and keeps the barrier high even at high spin.

Times Cited Count:3 Percentile:68.41(Physics, Nuclear)Fission barrier heights of No have been determined through the entry distribution method. The entry distribution is the initial distribution of excitation energy and spin from which the
deexcitation starts in the fusion-evaporation reaction. The initial distribution is extracted from measured
-ray multiplicity and total
-ray energy. This paper describes the details of the entry distribution method, and reports the first determination of the fission barrier heights of
No, which is the heaviest nucleus whose fission barrier has been measured.

Times Cited Count:68 Percentile:94.96(Physics, Nuclear)Heavy neutron-rich nuclei were populated via the fragmentation of a E/A=1 GeV Pb beam. Secondary fragments were separated and identified and subsequently implanted in a passive stopper. By the detection of delayed
rays, isomeric decays associated with these nuclei have been identified. A total of 49 isomers were detected, with the majority of them observed for the first time. Possible level schemes are constructed and the structure of the nuclei discussed. To aid the interpretation, shell-model as well as BCS calculations were performed.

Times Cited Count:33 Percentile:84.74(Physics, Nuclear)We have identified an isomer with a half-life of 17 s in
Rf through a calorimetric conversion electron measurement tagged with implanted
Rf nuclei using the fragment mass analyzer at Argonne National Laboratory. The low population yield for this isomer suggests that this isomer should not be a 2-quasiparticle high-
isomer which is typically observed in the N = 152 isotones, but should be a 4-quasiparticle one. Possible reasons of the non-observation of a 2-quasiparticle isomer are this isomer decays by fission with a half-life similar to that of the ground state of
Rf. Another possibility, that there is no 2-quasiparticle isomer at all, would imply an abrupt termination of axially symmetric deformed shape at Z=104.
