Abstract

A method is developed for the calculation of non-normal parity vibration and single-particle strength functions for nuclei with one nucleon outside a doubly closed shell. The coupled linearized equations for the amplitudes of excitation of the states of the odd-mass nucleus are obtained by considering the equation of motion of the odd nucleon. This is accomplished by employing an expansion in terms of a complete set of states of the closed-shell core, yielding a hermitian matrix.

The states of the core are treated by the hole-particle-RPA method. Numerical calculations are presented for 17O. It is found that no single phonon-coupled or single-particle state occurs below 5 MeV.
