The study on the triple differential cross section (TDX) and the proton-neutron (pn) pairing strength V-0 in the O-16(p, pd) reaction reveals a clear correspondence between them. This suggests that the (p, pd) reaction could be a promising tool for investigating isoscalar pn pairs in nuclei.
Background: The isoscalar pn pair is expected to emerge in nuclei having the similar proton and neutron numbers but there is no clear experimental evidence for it. Purpose: We aim to clarify the correspondence between the pn pairing strength in many-body calculation and the triple differential cross section (TDX) of proton-induced deuteron knockout (p, pd) reaction on O-1(6). Methods: The radial wave function of the isoscalar pn pair with respect to the center of O-1(6) is calculated with the energy density functional (EDF) approach and is implemented in the distorted wave impulse approximation framework. The pn pairing strength V-0 in the EDF calculation is varied and the corresponding change in the TDX is investigated. Results: A clear V o dependence of the TDX is found for the O-16(p, pd) 14N(1(2)(+)) at 101.3 MeV. The nuclear distortion is found to make the V-0 dependence stronger. Conclusions: Because of the clear V-0-TDX correspondence, the (p, pd) reaction will be a promising probe for the isoscalar pn pair in nuclei. For quantitative discussion, further modification of the description of the reaction process will be necessary.
