- 論文の詳細を見る
On the basis of np phase shifts reported in the preceding paper, we suggest an isospin I=0 np resonance as responsible for the structures observed in three of four independent quantities. The most plausible candidate is the ^1F_3 state. Its Breit-Wigner parameters are M_R ^2.19 GeV, Γ_<el>^50 MeV and Γ_<el>/Γ^0.12. This structure in the ^1F_3 wave explains half of the observed sharp rising of the σ_r(I=0) above 1.1 GeV/c and is compatible with the experimental peak in the Δσ_L(I=0) as well as with the shoulder in the σ_<tot>(np) around 1.4 GeV/c.
