Reaction and anomalous contribution of the P wave in the system near the threshold
Dal'karov O. D. , Protasov K. V.
The anomalously large Pwave intensification of the reaction pp -> ΛΛ at energies near the threshold ΛΛ, which was observed experimentally, can be explained theoretically by the existence of quasinuclear levels in the ΛΛ system.
