Description

The dependences of the elastic scattering differential cross sections and total cross sections for Λ3H and Λ6He hypernuclei on the magnitude of the nuclear edge diffuseness, the binding energy of the incident hypernuclei, on the finite ranges of the nuclear forces between clusters in hypernuclei, and on processes of multiple (double and triple) scattering are calculated with the use of the obtained convenient general formulae for elastic scattering amplitudes of two- and three-cluster weakly-bound nuclei on spherical nuclei for arbitrary dependence of profile functions on the impact parameter. The influence on the behavior of the cross sections during transition from two-cluster model to three-cluster one for the studied hypernuclei, is clarified as well

Abstract (Russian)

Представлены записанные в удобном для расчетов виде общие формулы для амплитуд дифракционного рассеяния двух- и трехкластерных слабосвязанных ядер на сферических ядрах при произвольной зависимости профильных функций от прицельного параметра. Получены выражения для дифференциальных сечений упругого рассеяния гиперядер Λ3H и Λ6He и полных сечений с учетом величины размытия края ядра-мишени, энергии связи налетающих гиперядер, радиусов действия ядерных сил между кластерами в гиперядрах, процессов многократного (двух- и трехкратного) рассеяния, а также выяснено влияние на поведение сечений перехода от двухкластерной к трехкластерной модели для названных ядер
