On positive-parity states of⁴⁵Sc,⁴⁷Sc and⁴⁹Sc

Abstract

The 46,48,50Ti(d,3He)45,47,49Sc reactions have been investigated at an incident energy of 52 MeV. Angular distributions have been measured and spectroscopic factors have been deduced by means of a DWBA analysis. Positive-parity states have been found up to about 9 MeV excitation energy, revealing about 70% of the 1d5/2 proton-hole strength. The 2s1/2, 1d3/2 and 1d5/2 strength distributions are compared with predictions from phonon-hole coupling calculations.
