Core excitations in (d,p) reactions including transitions to continuum levels

Effects of core excitations in (d, p) reactions are investigated for ¹²C(d, p)¹³C¹ reactions in the CCBA framework, where couplings of channels are considered for the ground and first-excited levels of ¹²C in the initial state and for the bound $\text{1}\text{2}{}^{\mathrm{+}}\text{and}\text{5}\text{2}{}^{\mathrm{+}}$ levels and low-lying continuum levels of ¹³C in the final state, where a discretization is introduced for the continuum region. In the transitions to the continuum levels, matrix elements are calculated by the use of scattering-state wave functions for the final neutron. Theoretical cross sections and vector analyzing powers are compared with experimental data, where significant contributions of core-excitation processes are identified, particularly in the transition to the $\text{5}\text{2}{}^{\mathrm{+}}{}_{\mathrm{II}}$ level of ¹³C. Spectra of emitted protons are calculated and compared with the measured ones. Adequate agreement between theory and experiment is found throughout the present investigation.
