We study theoretically the feasibility of the semi-exclusive 12C(p,dp)X reaction for the observation of η^′ mesic nuclei using the microscopic transport model JAM. The semi-exclusive measurements of the (p,d) reaction with protons from η^′ absorption are found to be significant for the observation of the η^′ bound states. Especially, the measurements of the energetic protons from η^′ non-mesic two-body absorption (η^′ NN → NN) are considered to be critically important. The Green's function method is used to calculate the expected spectrum of forward going deuterons corresponding to the excitation energy spectrum of the η^′ ⊗ 11C system in the semi-exclusive measurement. The semi-exclusive measurements are shown to be important in general for the η^′ mesic nucleus observation.
