Image of FIG. 1.
FIG. 1.

Final state summed differential cross section for the reaction obtained by experiment and QCT; the experimental result is multiplied by an arbitrary scaling factor. 180° corresponds to backward (rebound) scattering of the positive charge carrier.

FIG. 2.

Schematic illustration of important processes impacting final Rydberg-atom detection in a crossed-beam experiment.

Image of FIG. 3.
FIG. 3.

Transition probability of RE after impulsive collision at , from initial state (, ) and averaged over all initial , going to final summed over all (, ). Open circles denote the quantum mechanical sudden approximation, and points denote the classical impulse approximation.

FIG. 4.

Radiative lifetime of field-free hydrogen states and Stark states at with a field strength of . Open symbols denote the Stark lifetimes, and the solid circles denote the field-free lifetimes.

Image of FIG. 5.
FIG. 5.

Angular dependence of attenuation of RE signal (fraction of total signal lost) for laser polarization in the and directions. The polarization is parallel to the initial velocity of the H atom. The upper panel displays the total attenuation, while the lower three panels show the separate contributions from each loss mechanism. A scattering angle of 180° corresponds to backward (rebound) scattering of the positive charge carrier.

FIG. 6.

Population of states for forward/backward scattering for initial state (, , ). Solid points denote forward scattering , and open points denote backward scattering .

Image of FIG. 7.
FIG. 7.

Angular dependence of the total attenuation of the RE (fraction of total signal lost) for different collision complex lifetimes (ps). Successive curves are offset by 0.01 to facilitate comparison. 180° corresponds to backward (rebound) scattering of the positive charge carrier.

Image of FIG. 8.
FIG. 8.

Angular dependence of the total attenuation of the RE signal (fraction of total signal lost) for different product states. Successive curves are offset by 0.01 to facilitate comparison. 180° corresponds to backward (rebound) scattering of the positive charge carrier.

Image of FIG. 9.
FIG. 9.

Angular dependence of attenuation of RE signal for different mechanisms in the absence of an applied electric field. 180° corresponds to backward (rebound) scattering of the positive charge carrier. Results are shown for both polarized excitation lasers.
