The structure and properties of45Sc at low excitation energies

Abstract

The spins and electromagnetic properties of levels in 45Sc up to 2,352 keV were studied by means of inelastic proton scattering using a 3-parameter coincidence arrangement and Coulomb excitation with 3He and 4He beams. Relevant experimental results are discussed in terms of the Thankappen-True core-plus-particle model.

Properties of levels in22Ne

“…Olivier cidence arrangement was similar to those discussed by Buitendag et al [3]. The incoming alpha particles were accelerated to an energy of 12.0 MeV with the 6 MV Van de Graaff accelerator of the National Accelerator Centre (NAC) at Faure, South Africa.…”

“…Coincident protons and gamma rays from the 19F(o~,py)22Ne reaction were recorded with a 3-parameter coincidence arrangement as described by [3]. Coincident protons and gamma rays from the 19F(o~,py)22Ne reaction were recorded with a 3-parameter coincidence arrangement as described by [3].…”

Nuclear levels in43Sc at low excitation energies

“…2. According to previous studies [6,7] the influence of angular distribution effects on branching ratios is negligible for nuclei with high ground state spins as is the case for 43Sc with a ground state spin of 7/2-.…”

Properties of low-lying levels of59Co

“…A threeparameter computer-orientated coincidence arrangement using a series 50/50 Nuclear Data analyser coupled to a PDP-15 computer was used in order to study levels up to approximately 3 MeV. The experimental method has been described previously [3]. To minimize the influence of Doppler shifts, the coincident gamma rays were detected at an angle perpendicular to the direction of residual nuclei associated with 2MeV excitation.…”

“…Two Si surface-barrier detectors located at + 110 ~ and -110 ~ with respect to the incident beam and a 42 cm 3 Ge(Li)-detector at 90 ~ were used in a 3-parameter computer-orientated coincidence arrangement. The experimental method has been described previously [3]. The coincidence gamma spectra were recorded over 8192 channels.…”
