In this work the angular distributions of the α-particles leading to the first five levels of25Mg, in the reaction28Si(n, α)25Mg, are analysed. They are obtained by means of a telescope device consisting of two silicon semiconductor detectors. If one supposes that these angular distributions are due partially to a statistical effect, partially to a «heavy stripping process» one can correctly explain both their shape and their absolute value.

In questo lavoro vengono analizzate le distribuzioni angolari delle particelle α emesse nella reazione28Si(n, α)25Mg, corrispondenti ai primi cinque livelli del25Mg, ottenute per mezzo di un telescopio costituito da due rivelatori semiconduttori al silicio. Esse vengono interpretate come dovute in parte ad un effetto statistico ed in parte ad un effetto diretto di «heavy particle stripping». Tale interpretazione permette di preve-derne correttamente sia la forma che il valore assoluto.
