Summary
A theoretical model which describes in a single picture the evaporation component and the nonequilibrium component of the reaction fragment-light-particle angular correlation is discussed. Physical interpretations of some analytic results are presented. The few parameters contained in closed semi-classical expressions obtained for the in-plane differential multiplicities are connected, in an explicit manner, to the mechanism of the process considered. As an example, the application to the in-plane C-α differential multiplicity from the16O(101 MeV) +48Ti deeply inelastic collision is quoted.
Riassunto
Si discute un modello teorico che descrive in una singola descrizione la componente evaporativa e la componente di nonequilibrio della correlazione angolare frammento di reazione-particella leggera. Sono presentate interpretazioni fisiche di alcuni risultati analitici. I pochi parametri contenuti in concise approssimazioni semiclassiche ottenute per le molteplicità differenziali nel piano sono collegati, in modo esplicito, al meccanismo del processo considerato. Come esempio si riporta l’applicazione alla molteplicità differenziale C-α nel piano dalla collisione profondamente anelastica16O(101 MeV)+48Ti.
Реэюме
Обсуждается теоретическая модель, которая описывает в единой картине испарительную компоненту и неравновесную компоненту угловой корреляции между фрагментами реакции и легкими частицами. Предлагаются фиэические интерпретации некоторых аналитических реэультатов. Рассматривая механиэм реакции, можно свяэать несколько параметров, содержашихся в эамкнутых кваэиклассических выражениях, полученных в плоскости дифференциальных множественностей. Как пример, рассматривается дифференциальная множественность C-α в плоскости для глубоко неупругого столкновения16O(101 МзВ) +48Ti.
