The Asymmetry

A cylindrical asymmetry about the direction of motion of 5Li has been seen in the breakup of the ground state of this nucleus observed as an intermediate state in the reaction 6Li(3He, pα)4He. Measurements were made at bombarding energies of 1.00, 1.25, and 1.50 MeV with isotopically enriched LiF targets using a two-dimensional analysis technique. We explain both the rough magnitude of the asymmetry and its qualitative energy dependence in terms of a simple semiclassical model. In this model the origin of the asymmetry is associated with the short life of the 5Li intermediate state and with the memory retained by the proton during this short life of its "localization" at the time of formation of 5Li.

Bombarding Energy

A thin gas target was used and the particles from the reactions were detected by a proportional counter. The results show that the total cross-section for the two reactions is the same to within 1%, but that the angular distributions of the products are significantly different. The asymmetry coefficient for the reaction D( d , n ) 3 He is given by 0·31 + 0·0058 E , compared with 0·13 + 0·0047 E for reaction D( d , p ) 3 H, where E is the bombarding energy in kilovolts.

A description is given of a 1 MV, electrostatic generator and ancillary equipment which has been used to study the asymmetry in the angular distribution of α-particles from the Li7 (p, α) He4 reaction. The angular distribution of the a-particles is given by the expression Y(θ) =Y(90�)[1 +A(E) cos2θ + B(E)cos4 θ] where A(E) and B(E) are functions of the proton energy. The form of the expression implies the existence of both p and f protons in the nuclear reaction.
