Description

Particle-hole excitations near closed shells carry information on single-particle energies and on two-body interactions. The particle-hole excitations near the doubly magic nuclei are of special interest. Information on the charge-changing particle-hole excitations (T= 5 negative parity states) in $^{48} $ Ca is not available. We performed an experiment to establish the level scheme of the low-lying negative parity T= 5 states in $^{48} $ Ca. Excitation functions for the $^{1} $ H ($^{47} $ K, p) $^{47} $ K (gs) and $^{1} $ H ($^{47} $ K, p) $^{47} $ K (3/2$^+ $) reactions in the cm energy range from 1 MeV to 4.5 MeV were measured. The T= 5 states are expected to show up in the p+ $^{47} $ K excitation function as narrow resonances. This experiment was performed at NSCL using the ReA3 beam of $^{47} $ K at energy of 4.6 MeV/u. ANASEN, set in active target mode, was used for this experiment. Experimental results from this experiment will be presented.
