Shape parameters of a weakly deformed ground-state band and highly slightly triaxial sideband in $^{42}\mathrm{Ca}$ were determined from $E2$ matrix elements measured the first low-energy Coulomb excitation experiment performed with AGATA. The picture two coexisting structures is well reproduced by new state-of-the-art large-scale shell model beyond-mean-field calculations. Experimental evidence for superdeformation built on ${0}_{2}^{+}$ has been obtained role triaxiality...
We examine the behavior of width giant dipole resonance (GDR) at high excitation energies and show, based on new detailed measurements together with a reanalysis previous experimental results, that GDR in Sn nearby mass compound nuclei continues to increase up final-state temperatures $T\ensuremath{\sim}3.2\mathrm{MeV}$. These correspond highest which can be extracted reliably from existing data.

By comparison with data literature lower energy, we conclude a better symmetry these nuclei high energy.
