Abstract

The electric quadrupole moment Q for the ground state of 32Al has been measured using the β-NMR technique. Spin-polarized 32Al nuclei were obtained from the fragmentation of 40Ar projectiles at E/A = 95 MeV/nucleon, and were implanted in a single crystal α-Al2O3 stopper. The quadrupole moment was deduced from the measured quadrupole coupling constant. The obtained value, |Q(32Alg.s.)| = 24(2) mb, was well reproduced by shell model calculations within the sd shell, indicating that 32Al is a normal sd-shell nucleus. The result is in sharp contrast to the strongly deformed nuclei 32Mg and 31Mg neighboring the 32Al isotope. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]

Abstract

The development of techniques to produce low-energy spin-polarized radioactive nucleon beams (RNBs) is reported. It employs the inverse-kinematics reactions of law energy heavy-ion beams for the RNB production with in-flight separator. Some plans of research are discussed that apply these well-focused, conveniently energetic spin-polarized RNB to nuclear structure physics and material science. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]
