The seniority-zero excited-state spectrum of the Hamiltonian is studied in detail. Approximate excited-state wave functions of the form are developed. These solutions are compared with exact solutions of a small system and the agreement is quite good. A somewhat larger system is studied in order to see how the excited-state spectrum changes as the number of separable functions is increased. The method is applied to heavy nuclei and is in good agreement with observed excited states for nuclei having 144 to 150 neutrons. A theoretical spectrum is displayed for each even neutron system from 144 to 152 neutrons.
