| Abstract: | We assume that the state of the MIT bag model describes a hadron which itself is confined to a spherical region of certain size. By demanding that the low energy levels of the quark system and that of the confined hadron coincide we determine selfconsistently all relevant parameters and calculate the Roper resonance mass. |
