Description
The N=116 chain from Z=78 towards Z=70 shows a clear indication of unexpected nuclear shape behavior. The drop of the 4$^{+}$ to 2$^{+}$ excitation energy ratio, E(4$^+$)/E(2$^+$) seen from $^{190}$Os to $^{190}$W doesn't follow the systematic expectations in the neighboring nuclei. Experimental and theoretical efforts have been made to understand the structure of $^{190}$W that remains mostly unexplained. The lifetime of the 4$^{+}$ state in $^{190}$W will provide relevant information on the collectivity of this state and an insight into the nuclear structure in this mass region.
