In a phenomenological approach, the + core structure is investigated in the 
Ne, 
Ti, 
Mo, 
Te, and 
Po nuclei through the local potential model using a double-folding nuclear potential with effective nucleon-nucleon interaction of M3Y + 
type, where the term acts only between the saturation regions of -cluster and core. Properties such as energy levels, -widths, B(E2) transition rates, and half-lives are calculated, and good level of agreement with experimental data is obtained in general. It is shown the inclusion of the term is determinant for a better description of the experimental energy levels compared to the ground state bands produced with the simple M3Y interaction. The properties calculated for Te reinforce the superallowed -decay feature for this nucleus, as indicated in previous studies.
