Abstract

The differential spectra of final particles in the reaction \(pn\to pp\pi^{-}\) are presented according to data obtained at nine energy values with the aid of a deuterium-filled bubble chamber. These spectra are compared with the results of a partial-wave analysis of data obtained with a continuous neutron beam incident to a proton target. This analysis was used as basis for performing a global partial-wave analysis of data on proton–neutron, neutron–proton, and proton–proton collisions. As a result, it became possible to determine the contributions of both isovector and isoscalar partial waves to a precision substantially higher than that reached earlier.

摘要

在反应最终颗粒的差分光谱\（{ - } PN \到第\ PI ^ \）根据在9个的能量值与氘填充气泡室的辅助下获得的数据呈现。将这些光谱与对入射到质子目标的连续中子束获得的数据进行部分波分析的结果进行比较。该分析被用作对质子-中子，中子-质子和质子-质子碰撞数据进行全局分波分析的基础。结果，有可能确定等矢量和等量分波的贡献，使其精度大大高于早先达到的精度。
