J. Gao et Jb. Delos, QUANTUM MANIFESTATIONS OF BIFURCATIONS OF CLOSED ORBITS IN THE PHOTOABSORPTION SPECTRA OF ATOMS IN ELECTRIC-FIELDS, Physical review. A, 56(1), 1997, pp. 356-364
The methods developed in the preceding paper (paper II) are used to co
nstruct a wavefunction near a bifurcation of classical orbits of an at
omic electron in an electric field. A formula for the recurrence stren
gth near the bifurcation is derived and compared with experimental mea
surements.
