Light proton-rich bound and unbound nuclei were produced by means of stripping reactions of secondary beams of Mg and Ne. The decays of the unbound nuclei Na have been measured by detecting their decay products Ne and one proton and by performing an invariant-mass reconstruction. For Na, the present work is the first measurement of its decay. As the decay scheme of this nucleus could not be det...

Large-scale shell model calculations were performed for neutron-rich even-even Te using a realistic effective interaction derived from CDBonn nucleon-nucleon potential for the positive and negative parity states. The calculated results are compared with the recently available experimental data. The transition rates B(E2; 0 →2) are also calculated by taking into consideration core polarization e...

A very exotic process of β-delayed fission of 180Tl is studied in detail by using resonant laser ionization with subsequent mass separation at ISOLDE (CERN). In contrast to common expectations, the fission-fragment mass distribution of the post-β-decay daughter nucleus 180Hg (N/Z=1.25) is asymmetric. This asymmetry is more surprising since a mass-symmetric split of this extremely neutron-defici...

A systematic study of high energy, one-neutron removal reactions on 23 neutronrich, psd–shell nuclei (Z = 5−9, A = 12−25) has been carried out. The longitudinal momentum distributions of the core fragments and corresponding single-neutron removal cross sections are reported for reactions on a carbon target. Extended Glauber model calculations, weighted by the spectroscopic factors obtained from...

We discuss properties of the quadrupole collective excitation of the deformed neutronrich nucleus Mg within the framework of quasi-particle random phase approximation (QRPA). We first solve the coupled-channels equations to obtain the single-particle levels, and construct the ground state by treating the pairing correlations in the BCS approximation. We then solve the QRPA equation using the re...
