Anomalous P wave in
scattering at low energies; the

Dal'karov 0. D. , Protasov K. V.
Calculations are carried out in a quasinuclear coupled-channel model on the behavior of the ratio of real and imaginary parts of the amplitude for forward pN scattering and on the nuclear shifts of the \S and IP levels of the/?/? atom. The results of the calculations indicate an anomalously large P-wave contribution resulting from quasinuclear NN resonances.
