An axial asymmetry about, the direction of motion of Li⁵ has
been seen in the breakup of the ground state of this nucleus as an intermediate
state in the reaction Li⁶(He³,pα)He⁴. The total cross section for this process
was found to be a few hundred millibarns, an order of magnitude greater than
predicted by a statistical model calculation, and the asymmetry amounts to
a factor of 2.0 ± 0.3 in the double, differential cross section. It is shown
that this asymmetry in the secondary decay of the sequential breakup process
can arise from the memory retained by the intermediate state of its structure
during the primary reaction, in which a neutron is transferred from Li⁶ to
He³. It was found that the strength of the asymmetry is sharply dependent upon the duration of the final state interaction. This confirms the proposed interpretation and suggests that further data could lead to useful information regarding correlation of the p-shell nucleons in the Li⁶ ground state. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
