Description

A phenomenological analysis of the channels for three- and four-α-particle in 16Op collisions at 3.25 A GeV/c for the 4π-geometry conditions is carried out for the first time. Azimuthal asymmetries and collinearity observed experimentally are interpreted in the frame of phenomenological model, that asymmetries are conditioned by the transverse motion of fragmented nucleus. It is found that the mean value of transverse momentum of α particles and the collinearity of their emission in the reaction plane are almost independent of the transverse momentum of the fragmented nucleus

Abstract (Russian)

Впервые в условиях 4π-геометрии проведен феноменологический анализ каналов образования трех и четырех α-частиц в 16Op-соударениях при 3.25 А ГэВ/с. Экспериментально наблюдаемые азимутальные асимметрии и коллинеарность описаны в рамках феноменологической модели, предполагающей возбуждение ядра периферическим, а его распад статистическим. Показано, что азимутальные асимметрии обусловлены поперечным движением фрагментирующего ядра. Обнаружены независимость среднего значения поперечного имульса α-частиц и коллинеарность их вылета в плоскости реакции от получаемого ядром поперечного импульса
