Abstract

Abstract The energy levels of 47 Sc are investigated through the 45 Sc(t, p) 47 Sc reaction using 11.8 MeV incident tritons and a multigap magnetic spectrograph with nuclear emulsions to analyse the resulting protons. Seventy states are excited in 47 Sc up to 6.9 MeV. The data are analysed using the distorted wave Born approximation and values of the orbital angular momentum L of the transferred neutron pair are derived for 28 levels. Good agreement with previous results is generally obtained, new states in 47 Sc are detected and more precise information on the spins of some levels in 47 Sc are deduced. The results are compared with shell model calculations. Strong L = 0 and mixed L = 0 + 2 transitions to 47 Sc levels other than the ground state are detected, and qualitative explanations for them are presented.
