Harmonic oscillator with a δ-function potential is analysed and compact expressions are obtained for the energy eigenvalues of the even parity states. These energies tend to the energy eigenvalues of the odd parity states for large strengths of the δ-function potential, leading to degenerate states in the limiting cases. The WKB analysis and model wavefunctions are developed which provide accurate values for the energies and an insight into the physical structure.
