Intermediate Energy NN Phase Shifts. II

N. Hoshizaki, T. Watanabe
1991 Progress of theoretical physics  
321 Neutron-proton phase-shift analyses with and without /=0 absorption are performed in the range from 430~800 MeV with the /=1 phases being fixed to those values given previously. Solutions with / = 0 absorption are better, in particular at 625 and 645 MeV, and reveal a narrow resonance in the I P, wave.
