Shape evolution and Gamow-Teller β-decay of neutron-rich A∼100 nuclei within beyond-mean-field approach

Our recent investigations represent an attempt to the self-consistent description of exotic phenomena in neutron–rich A∼100 nuclei [1, 2] within the complex Excited Vampir variational model with symmetry projection before variation using a realistic effective interaction in a large model space. The triple shape coexistence and the shape evolution in the N=58 Sr and Zr isotopes, the shape evolut...

Shape coexistence and charge radii in the lead region studied by in-source laser spectroscopy at RILIS-ISOLDE

The competition between spherical and deformed configurations gives rise to shape coexistence in the neutron-deficient isotopes around Z~82 and N~104 [1] while on the neutron-rich side, effects due to octupole deformation in the vicinity of N~133 could be expected [2]. In order to determine to which extent the ground and isomeric states of these nuclides are affected by these phenomena, an exte...

Low-lying level structure of the neutron-rich nucleus

The neutron-rich nuclei Nb and Zr have been populated using in-flight fission of a U beam at 345 MeV/nucleon at the RIBF facility. A T1/2 = 150(30) ns isomer at 313 keV has been identified in Nb for the first time. The low-lying levels in Nb have been also populated following the β-decay of Zr. Based on the difference in feeding pattern between the isomeric and β decays, the decay scheme from t...

β-decay half-lives of very neutron-rich Kr to Tc isotopes on the boundary of the r-process path: an indication of fast r-matter flow.

The β-decay half-lives of 38 neutron-rich isotopes from (36)Kr to (43)Tc have been measured; the half-lives of (100)Kr, (103-105)Sr, (106-108)Y, (108-110)Zr, (111,112)Nb, (112-115)Mo, and (116,117)Tc are reported here. The results when compared with previous standard models indicate an overestimation in the predicted half-lives by a factor of 2 or more in the A≈110 region. A revised model based...

  Neutron scattering is proved to be a vital probe in unveiling the magnetic properties of high temperature superconductors (HTSC). Detailed information about the energy and momentum dependence of the magnetic dynamics of HTSC have been obtained directly by this technique. Over the past decade by improving the crystal growth methods, large and high quality single crystals of HTSC, which are ess...
