Four-Body Wave Function of pi sup 3 He-System at the Threshold Energy

摘要

On the basis of approximate four-body equations the wave function of pi sup 3 He-system is calculated at zero kinetic energy of the pion. In the case when distances between all four particles are comparable with the nucleus size a strong distortion of the wave function of (3N)-subsystem caused by the presence of the pion is found. The calculated four-body function is represented in a semianalytical form, which makes it possible to apply it in different calculations. 14 refs.; 1 tab. (Atomindex citation 17:061080)
