Abstract
It is suggested that the Roper resonance is primarily an + (-wave pair) self-consistent bound state Calculations are done with a simple model, coupled , channels in the , state, where is a -wave state with mass 700 MeV. When the channel is neglected, the is self-consistently generated by the exchange force in the channel. When the channel is included, the bootstrap survives, and is stable against large variations in the cutoff associated with exchange.
