The one phonon γ-vibrational bands in 154Gd are compared with the theories existing at that time (1960) showing the best agreement with the rotation–vibration model of Faessler and Greiner. Nuclear shape coexistence was first discovered in both ⁷²Se and ^184–188Hg with the Frankfurt Generalized Collective Model reproducing the two different shapes. In recent years experimental evidences have been found for both one, two, and possibly three phonon γ bands in the A = 103–110 region including the first such bands in odd N-even Z and even N-odd Z nuclei. Cluster radioactivity predicted by Sandulescu, Poenaru and Greiner has been observed. Here, maximum cluster radioactivity is seen in the zero neutron emission in cold binary and ternary fission of ²⁵²Cf. Finally, recent super heavy element discoveries of the new elements 115, 117 and 118 are described. The half-lives in 117 which is closest in N to N = 184 on the Island of Stability support the theoretical predictions of the long-lived island.
