A very asymmetric two-center harmonic-oscillator shell model with different depths of
the potential wells was developed in order to study the dynamical effects on the alpha
decay widths. Only the one-dimensional (the z-component) problem was considered in detail,
allowing the use of a numerical procedure for finding the solution of the Schrödinger
equation. It is shown that such a model enhances the amplitudes of the single particle
wave functions in the vicinity of the surface of the mother nucleus relative to the
corresponding single-particle wave functions of the static one-center harmonic oscillator
model. Thus, the intrinsic alpha decay overlap integrals may increase values of the
amplitudes.
