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.

Zn in the Argonne National Laboratory, and an in-beam
-ray experiment were performed using the GRETINA array. The
and
levels of
Ni were observed for the first time. Those levels are regarded as large deformed states associated with proton excitation from the
orbit because they cannot be reproduced by a shell-model calculation assuming a small valence space without

Ni, and confirms the predictive power of the Monte Carlo shell-model calculation.
