Background: Proton-induced α-knockout reactions may allow direct experimental observation of α clustering in nuclei. This is obtained by relating the theoretical descriptions of clustering states to the experimental reaction observables. It is desired to introduce microscopic structure models into the theoretical frameworks for α-knockout reactions. Purpose: Our goal is to probe the α clustering in the Be10 nucleus by proton-induced α-knockout reaction observables. Method: We adopt an extended version of the Tohsaki-Horiuchi-Schuck-Röpke wave function of Be10 and integrate it with the distorted-wave impulse approximation framework for the calculation of (p,pα)-knockout reactions. Results: We make the first calculation for the Be10(p,pα)He6 reaction at 250 MeV by implementing a microscopic α-cluster wave function, and we predict the triple-differential cross section (TDX). Furthermore, by constructing artificial states of the target nucleus Be10 with compact or dilute spatial distributions, the TDX is found to be highly sensitive to the extent of clustering in the target nuclei. Conclusions: These results provide reliable manifestation of α clustering in Be10.
