Abstract

A group of odd-mass neutron-rich nuclei with neutron excesses of 9–11 in the 13<~Z<~17 region has been produced and studied by in-beam intermediate-energy Coulomb excitation using an array of NaI(Tl) detectors. The excitation energies of the observed states in 35Al, 37Si, 39P, 41S, 43S, and 45Cl have been measured, and the B(E2) values connecting these states to the ground states have been extracted. For the 41S and 43S cases the measurements have been compared to particle-rotor and particle-vibrator calculations. The measurements for 41S are consistent with an interpretation of the low-energy behavior of this nucleus as rotations of a deformed core, whereas for 43S no distinction can be made between the deformed (rotational) and spherical (vibrational) calculations.
