PAPH: Partial-wave analysis of p - 3 He scattering

Abstract
Partial wave analysis is a model independent method to determine the scattering amplitudes and study the n+p+^3 He system with various models of three body problem. A partial-wave analysis program called PAPH was used to determine the complex scattering amplitudes of elastic p-^3 He scattering via fitting the experimental data for many kinds of observables. It was developed by representing the S-matrix to carry out the analysis in elastic and inelastic regions.

Title of program: PAPH
Catalogue Id: ADMO_v1_0

Nature of problem
Partial-wave analysis (PWA) is a model independent method [1] to determine the scattering amplitudes by means of fitting the experimental data for many kinds of observables. PAPH can carry out the energy-independent PWA of p-3He scattering [2]. The obtained phase shifts can be used to construct the p-3He potential for studying the n+p+3He system with various models of three body problem.

摘要
分波分析（Partial wave analysis）是一种模型无关方法，可用于确定散射振幅，并借助各类三体问题模型研究n+p+^3He系统。本研究采用名为PAPH的分波分析程序，通过拟合多种可观测量的实验数据，求解弹性p-^3He散射的复散射振幅。该程序通过表征S矩阵（S-matrix），可在弹性与非弹性区域开展分析。

问题本质
分波分析（Partial-wave analysis, PWA）是一种模型无关方法[1]，可通过拟合多种可观测量的实验数据求解散射振幅。PAPH可对p-^3He散射开展与能量无关的分波分析[2]。所得相移可用于构建p-^3He相互作用势，以借助各类三体问题模型研究n+p+^3He系统。
