متن کاملShape coexistence in the neutron-deficient isotope
Neutron-deficient nuclei near the Z=82 closed shell exhibit the phenomenon of shape coexistence where the nucleus can take on oblate, prolate, and even spherical shapes at around the same excitation energy. The single-proton excitations in 187 Tl (with Z=81) can be used as a probe into the microscopic mechanisms behind this phenomenon. Previous studies of 187 Tl deduced the presence of coexisti...
متن کاملDeformation and its influence on the K isomerism in neutron-rich Hf nuclei
We investigate the influence of deformation on the possible occurrence of long-lived K isomers in Hf isotopes around N = 116, using configuration-constrained calculations of potential-energy surfaces. Despite having reduced shape elongation, the multi-quasiparticle states in Hf remain moderately robust against triaxial distortion, supporting the long expected occurrence of exceptionally long-li...
متن کاملIsospin-rich nuclei in neutron star matter
Stability of nuclei beyond the drip lines in the presence of an enveloping gas of nucleons and electrons, as prevailing in the inner crust of a neutron star, is studied in the temperature-dependent Thomas-Fermi framework. A limiting asymmetry in the isospin space beyond which nuclei cannot exist emerges from the calculations. The ambient conditions like temperature, baryon density and neutrino ...
متن کاملStructural evolution in the neutron-rich nuclei
The low-lying states in 106Zr and 108Zr have been investigated by means of β-γ and isomer spectroscopy at the RI beam factory, respectively. A new isomer with a half-life of 620±150 ns has been identified in 108Zr. For the sequence of even-even Zr isotopes, the excitation energies of the first 2+ states reach a minimum at N = 64 and gradually increase as the neutron number increases up to N = 6...
