The [Formula: see text] reaction on [Formula: see text] at incident proton energy of 300[Formula: see text]MeV is examined in the formalism of finite-range relativistic distorted-wave impulse approximation (FR-RDWIA). In comparison to conventional t-matrix model of Love–Franey, a new form of nucleon–nucleon t-matrix effective interaction is derived at 300[Formula: see text]MeV using Reid soft core potentials for isotopic spin one and taking into account the finite-range effects in the [Formula: see text] interaction at knockout vertex. In comparison to the conventional finite range nonrelativistic and relativistic formalism, the present formalism with a new version of [Formula: see text] t-matrix is effectively reproducing the shape of cross-section energy distributions for [Formula: see text], [Formula: see text] and [Formula: see text] states for asymmetric angle pair of [Formula: see text]–[Formula: see text]. Discrepancies between the experimental cross-section data and finite range theoretical calculations at [Formula: see text][Formula: see text]MeV are reasonably resolved in the present approach. Without any adjustable parameter of bound state, the obtained spectroscopic factors are in reasonably good agreement with the relativistic and nonrelativistic theoretical predictions by [Formula: see text], [Formula: see text] and [Formula: see text] analysis.
