Morishita, ToruWatanabe, ShinichiLin, C.

For simple wave packets, we showed that the measured momenta, when analyzed in appropriate coordinates, can reveal the stretching, the rotational, and the bending vibrational modes of their joint motion in momentum space, in spite of the Coulomb distortion in the final states.© American Physical Society (APS).
