| contents | Building on the spatial wormhole geometry proposed by Manton and Dunajski, we develop a modified model for the Neon-20 nucleus that incorporates a repulsive Coulomb potential. This reduces the large threshold energy for cluster break-up in the original model and converts most bound states to resonances. We use generalized WKB methods to calculate the energies of bound states, and also the energies and widths of under-barrier and over-barrier resonances. The results align closely with experimental data for the 0_1^+ , 0_1^- and 0_4^+ rotational bands of Neon-20, including the large widths in the higher-nodal 0_4^+ band. |
