The calculation of logft values and spectroscopic factors for nuclei in the mass range 10?15

Abstract

Wave functions obtained in previous shell-model calculations [1,2] for states of nuclei with masses A=10-15 are used to calculate logft values and spectroscopic factors. These wave functions, which were based on a modified surface delta two-body interaction, comprise the following active shell-model spaces: the lp3/2 and lp~/2 orbitals for mass 10 14 nuclei and restricted combinations of the lpl/2, 2Sl/2, lds/2 and ld3/2 orbitals for mass 15 nuclei, leading to four different calculations in the latter case. The calculated results support evidence that the modified surface delta interaction is a valid approximation to the effective interaction in light nuclei.

Study of transfer reactions in inverse kinematics with the TIARA array

“…In order to cope with the experimental difficulties which arise from the use of inverse kinematics [1,2] and low incident beam intensities, three state-of-the-art detectors have been coupled together for the first time. This report focuses on results obtained in the reaction d( 14 N,p) 15 N. This reaction has been widely studied in normal kinematics [3,4] and the structure of 15 N is very well described within the framework of the nuclear shell model [5][6][7]. Therefore, the same reaction in inverse kinematics provides a good opportunity to demonstrate the suitability of this complex experimental apparatus in studying the single-particle shell structure of exotic nuclei.…”
