Релятивистские сечения рассеяния системы двух частиц с потенциалами взаимодействия, содержащими «барьер»

Abstract

Квазипотенциальные уравнения для состояний рассеяния системы двух частиц с произвольным орбитальным моментом исследуются в релятивистском конфигурационном представлении. Рассмотрен случай сферически-симметричных потенциалов взаимодействия, содержащих «барьер». Представлены результаты численных расчётов сечений рассеяния, детально обсуждается их резонансное поведение. Проведён сравнительный анализ решений релятивистских и нерелятивистской задач.

Quasipotential equations for scattering states of a two-particle system with arbitrary angular momentum are investigated in the relativistic configuration representation. The case of spherically symmetric interaction potentials containing a “barrier” is considered. Scattering cross sections obtained from numerical calculations are presented, their resonant behavior is discussed indetail. Relativistic and non-relativistic results are compared.
