Energy dependent partial wave anlyses for the reaction rc-+p ':"'J+n are carried out with respect to S, P, D and F waves in the energy range 561-1300 MeV. Two different types of the solutions are obtained. In the first solution, the "'J-production peak is dominated by the S 11 resonance with mass M = 1570 MeV, total width TT = 140 MeV, branching ratios (S 11 res. --->rcN) I (S 11 res.->all) =40% and (S 11 res.-----'7"1JN)/(S 11 res.--'lall) =50%. In the second solution, it is dominated by the P 11 resonance with M=1580 MeV, TT=130 MeV, (P 11 res.-'TrcN)/(P 11 res.-----'7all) =35% and (P 11 res.-?"'JN)j(P 11 res.-'Tall) =305-~-This P 11 resonance is a new one which is different from Roper's resonance. In this analysis the second solution_ is better fitting experimental data than the first solution.P 11 and D 13 • When the peak is dominated by a resonance (called the Resonant Case) , we can consider the following three cases ;
