Mw. Beims et G. Alber, BIFURCATIONS OF ELECTRONIC TRAJECTORIES AND DYNAMICS OF ELECTRONIC RYDBERG WAVE-PACKETS, Physical review. A, 48(4), 1993, pp. 3123-3129
With the help of uniform semiclassical approximations the quantitative
connection between classical bifurcation phenomena and the dynamics o
f an electronic Rydberg wave packet in the presence of an external sta
tic magnetic field is discussed with particular emphasis on nongeneric
bifurcations of the Edmonds-Garton-Tomkins orbit.
