Using very high resolution coincidence techniques, we find a so-far unobserved fingerlike structure in the correlated electron momentum distribution. The structure can be interpreted as a signature of the microscopic dynamics in the recollision process. We identify features corresponding to the binary and recoil lobe in field-free (e; 2e) collisions. This interpretation is supported by analyzing ab initio solutions of a fully correlated three-dimensional helium model.
