Shell evolution of $$N$$ = 40 isotones towards $$^{60}$$Ca; First spectroscopy of $$^{62}$$Ti

Excited states in the $$N$$ = 40 isotone $$^{62}$$Ti were populated via the $$^{63}$$V($$p$$,$$2p$$)$$^{62}$$Ti reaction at $$sim$$200 MeV/nucleon at the Radioactive Isotope Beam Factory and studied using $$gamma$$-ray spectroscopy. The energies of the $$2_1^+ rightarrow 0_{rm gs}^+$$ and $$4_1^+ rightarrow 2_1^+$$ transitions, observed here for the first time, indicate a deformed Ti ground state. These energies are increased compared to the neighboring $$^{64}$$Cr and $$^{66}$$Fe isotones, suggesting a small decrease of quadrupole collectivity. The present measurement is well reproduced by large-scale shell-model calculations based on effective interactions, while ab initio and beyond mean-field calculations do not yet reproduce our findings.

Using angle-resolved photoemission spectroscopy and inelastic neutron scattering, we have studied how electronic structures and lattice dynamics evolve with temperature in Na-doped SnSe.

Azimuthal correlations of electrons from heavy-flavor decay with hadrons in $$p+p$$ and Au+Au collisions at $$sqrt{s_{NN}}$$ = 200 GeV

Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled $$p+p$$ collisions. Here we extend these studies to two particle correlations where one particle is an electron from the decay of a heavy flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interaction between heavy quarks and the quark-gluon matter. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to $$p+p$$ collisions.

Neutron-proton pairing competition in $$N=Z$$ nuclei; Metastable state decays in the proton dripline nuclei $$^{82}_{41}$$Nb and $$^{86}_{43}$$Tc

The low-lying structures of the self-conjugate ($$N=Z$$) nuclei $$^{82}_{41}$$Nb and $$^{86}_{43}$$Tc have been investigated using isomeric-decay spectroscopy following the projectile fragmentation of a $$^{107}$$Ag beam. These represent the heaviest odd-odd $$N=Z$$ nuclei in which internal decays have been identified to date. The resulting level schemes shed light on the shape evolution along the $$N=Z$$ line between the doubly-magic systems $$^{56}_{28}$$Ni and $$^{100}_{50}$$Sn and support a preference for $$T=1$$ states in $$T_z=0$$ odd-odd nuclei at low excitation energies associated with a $$T=1$$ neutron-proton pairing gap. Comparison with Projected Shell Model calculations suggests that the decay in $$^{82}$$Nb may be interpreted as an isospin-changing $$K$$ isomer.
