    通过求解N(N-)巴黎光学势的复薛定谔方程,研究了N(N-)系统的近阈束缚和共振行为,得到了一个p(p-)系统的 13P0共振态.发现其能量和宽度与最近BES用Breit-Wigner(B-W)公式分析J/ψ→γp衰变的实验数据给出的结果相容.讨论了这一结果的含义及进一步研究的建议.

    By solving the complex Schrdinger equation with the phenomenological Paris optical potential between nucleon(N) and antinucleon(N-),the near-threshold binding and resonant behaviors of the p-(p-)system are studied. As the result,a 13P0 resonance state of p is obtained. It is found that the energy and width of the state are compatible with the BES data in which the observed enhancement in the J/ψ→γp decay was fitted by a Breit-Wigner (B-W) formula either in the S-wave or in the P-wave.The indication of the results and the suggestion for the further theoretical investigation are discussed.
