Mechanisms of the sup 64 Zn(d, sup 6 Li) sup 60 Ni reaction at E sub lab = 16. 4 MeV
Cross-sections, A{sub y}, A{sub yy}, and A{sub xx} for the {sup 64}Zn(d, {sup 6}Li) reaction forming the ground and first excited states of {sup 60}Ni were measured in 5{degree} steps from {theta}{sub lab} = 25{degree} to 80{degree} using an E{sub lab} = 16.4 MeV beam of vector and tensor polarized deuterons. These data include the first measurement of A{sub xx} and A{sub yy} for the (d, {sup 6}Li) reaction on a medium to heavy target nucleus. The A{sub y} measurement is also among the first for (d,{sup 6}Li) reactions. Also measured were excitation functions of d{sigma}/d{Omega}, A{sub y}, A{sub yy}, and A{sub xx} for {sup 64}Zn(d,d) scattering at E{sub lab} = 16.4 MeV. The {sup 6}Li ground state and seven other wave functions, each representing {sup 6}Li continuum states of a given spin, I, and internal orbital angular momentum, l, l {le} 2, were included in coupled-channels (CC) calculations of {sup 60}Ni({sup 6}Li, {sup 6}Li) elastic scattering and finite-range, coupled channel Born approximation (CCBA) calculations for the {sup 64}Zn(d,{sup 6}Li) reaction forming the {sup 60}Ni ground state. This analysis is the first to consider the influence of {sup 6}Li continuum states on the (d, {sup 6}Li) reaction. The {sup 6}Li-{sup 60}Ni interactions were generated using a cluster folding model. Both the folding model and the CC and CCBA calculations were performed by the code FRESCO. For the {sup 64}Zn(d, {sup 6}Li) reaction, CCBA calculations demonstrated that {alpha} transfers forming the 3{sup +} state of {sup 6}Li affect d{sigma}/d{Omega} and A{sub y} very strongly.
