Description
The authors studied the 9Be(n,2n) reaction using double time-of-flight spectrometry, and found that it takes place mainly through the formation of 9Be* resonance states (6.76 and 7.94 MeV). The contribution of the direct process 8Be + n1 + n2 is small in spite of the weak binding (1.66 MeV) of the peripheral neutron p3/2 in the 9Be, compared with the incident energy En = 14.5 MeV. Measurements made at Φ1 = - Φ2 = 30o, 60o, 80o and at Φ1 = 30o, Φ2 =-15o show anisotropy of the (n,2n) reaction, predominantly towards the forward angles. (author)
Abstract (French)
Les auteurs ont etudie la reaction 9Be(n,2n) par double spectrometrie a temps de vol. On observe qu'elle se produit principalement par formation d'etats resonnants de 9Be* (6,76 et 7,94 MeV), la part du processus direct 8Be + n1 + n2 etant faible malgre l'etat peu lie (1,66 MeV) du neutron peripherique p3/2 dans 9Be, compare a l'energie incidente En = 14,5 MeV. Les mesures effectuees a Φ1= -0Φ2 = 30o, 60o, 80o et Φ1 = 30o, Φ2 = -15o ont montre une anisotropic de la reaction (n,2n) avec predominance vers les angles avant. (author)Additional details
