The correlated Tunneling Transfer Ionization (TuTI) channel in fast 4-body processes is utilized to probe the highly correlated asymptotic parts of the ground-state momentum space wave function. In this reaction, predominantly at large nuclear impact parameters, one electron in the ground state is captured by the proton by tunneling through the two-center barrier when electron and proton velocity vectors resonantly match. The measured 3-particle final-state momentum distributions show characteristic features that we trace back to the highly correlated non-s2 components of the ground-state momentum wave function. This conclusion is supported by a simple heuristic model.
