光学模型中的反质子-氘核氢原子态
Antiproton-deuteron hydrogenic states in optical models
摘要：
通过求解ppn系统的Faddeev方程，我们计算了最低类氢态的反质子-氘能级位移和宽度以及相应的pd散射长度和体积。得到了钯的湮没密度，并与氘的核密度进行了比较。研究了Trueman关系对复合颗粒的适用性。NN相互作用的强部分用两种不同的光学模型来描述，包括pp-nn耦合和n-p质量差，而NN则使用几种实际的相互作用。
英文摘要：
By solving the Faddeev equations for the ppn system, we compute the antiproton-deuteron level shifts and widths for the lowest hydrogenic states as well as the corresponding pd scattering lengths and volumes. The pd annihilation densities are obtained and compared to the nuclear density of deuterium. The validity of the Trueman relation for composite particles is studied. The strong part of NN interaction is described by two different optical models, including the pp-nn coupling and n-p mass difference, while for NN several realistic interactions are used.
