We develop a shell-model Monte Carlo method to calculate densities of states with varying exciton (particle-hole) number. We then apply this method to the doubly closed-shell nucleus ⁴⁰Ca in a full 0s-1d-0f-1p shell-model space and compare our results to those found using approximate analytic expressions for the partial densities. We find that the effective one-body level density is reduced by approximately 22% when a residual two-body interaction is included in the shell-model calculation.
