Abstract

Single-particle states in 49Ca have been investigated through the 48Ca(d, p)49Ca reaction initiated by vector-polarized deuterons of Ed = 56 MeV. Thirty-six levels were observed up to 8 MeV excitations. Transferred l, j values were deduced for these levels by measured angular distributions of cross section and analyzing power. We observed many additional states and corrected some previous jπ assignments. The total values of spectroscopic factors C2S obtained with zero-range distorted-wave-Born-approximation (DWBA) calculations are almost unity for the shells 2p 3 2, 2p 1 2 and 1f 5 2, and no 1f 7 2 states are observed. It is confirmed that 48Ca has a good closed-shell structure, the feature of which is consistent with occupation probabilities predicted from an extended second RPA theory.
