  In the framework of the isospin-dependent Boltzmann-Uehling-Uhlenbeck
transport model, nuclear bubble configuration in the hypothetical $^{48}$Si
nucleus is studied by proton induced central reaction at an incident beam
energy of 0.8 GeV/nucleon. It is found that along the beam direction more
energetic protons are emitted with bubble configuration in the target. In the
forward angles, compared with the case without bubble configuration, less
scattered energetic protons are emitted with bubble configuration in the
target. We thus provide a new way to probe the bubble configuration in nuclei.
