Description

Proton-rich nuclei in the A$\sim$70 region manifest exotic structure and dynamics generated by the interplay of shape coexistence and mixing, competing like-nucleon and neutron-proton T=1 and T=0 pairing correlations, and isospin-symmetry-breaking interactions. Their properties could bring insights into fundamental symmetries and interactions of relevance for the astrophysical $rp$ process. In particular the $\beta$-decay properties of the Z=N+2 members of the isovector triplets are expected to reveal fingerprints of T=0 pairing. Self-consistent results on isospin-related phenomena in A$\sim$70 nuclei within $complex$ Excited Vampir beyond-mean-field model using an effective interaction derived starting from Bonn CD potential have been recently obtained [1]. Weak interaction rates under terrestrial and stellar conditions have been also investigated [2]. We will present an unitary scenario of these related phenomena suggesting challenges for future experiments according to our predictions.\\ \noindent [1] A.~Petrovici, Phys. Rev.
