Precision measurement of the angular distribution for the 16O(d, p)17O transfer reaction to the ground state of 17O

Abstract The mechanism of the (d, p) reaction, which has been proven a powerful spectroscopic tool, is believed to be reasonably well understood. However, the 16 O(d, p) 17 O reaction leading to the ground state in 17 O seems to be a possible exception. It was found in the previous experiments that the 16 O(d, p) 17 O angular distribution exhibits a rapid decline below the peak at the angle of 15 degrees. To date this abnormal behavior has not been reproduced by theoretical models. In this work we present a re-measurement of the 16 O(d, p) O g . s . 17 angular distribution by using a high-precision magnetic spectrograph. Our new angular distribution shows a slower decline than the previous data do. A comparative analysis with the distorted Born approximation (DWBA), the adiabatic distorted wave approximation (ADWA) and the continuum discretized coupled channels (CDCC) method suggests that the drop of the differential cross sections at the forward angles is due to the deuteron breakup coupling effects. In addition, we extracted the spectroscopic factor (SF) and the asymptotic normalization coefficient (ANC) for the 17 O ground state.
