Effects of 6Li excitation in 64Zn(d

Abstract

Cross sections and the analyzing powers ${\mathit{A}}_{\mathit{y}}$, ${\mathit{A}}_{\mathit{y}\mathit{y}}$, and ${\mathit{A}}_{\mathit{x}\mathit{x}}$ for the $^{64}\mathrm{Zn}$(d${,}^{6}$Li${)}^{60}$Ni reaction forming the ground and first-excited states of $^{60}\mathrm{Ni}$ are measured in 5\ifmmode^\circ\else\textdegree\fi{} steps from ${\mathrm{\ensuremath{\theta}}}_{\mathrm{lab}}$=25\ifmmode^\circ\else\textdegree\fi{} to 80\ifmmode^\circ\else\textdegree\fi{} using a 16.4-MeV vector- and tensor-polarized deuteron beam. The $^{6}\mathrm{Li}$ ground state and seven other states, each representing $^{6}\mathrm{Li}$ continuum states of a given spin and internal orbital angular momentum, are included in finite-range, coupled-channel Born approximation (CCBA) calculations for $^{64}\mathrm{Zn}$(d${,}^{6}$Li${)}^{60}$Ni. The CCBA calculations demonstrate that \ensuremath{\alpha} transfers forming these continuum states, particularly those forming the first ${3}^{+}$ state in $^{6}\mathrm{Li}$, affect the $^{64}\mathrm{Zn}$(d${,}^{6}$Li${)}^{60}$Ni cross sections and analyzing powers strongly.
