Abstract

We investigate the energy and angular distribution of electrons emitted in fast collisions with neutral atoms from Rydberg states of the projectile into low-lying continuum states of the projectile. We find highly anisotropic, approximately ellipsoidal angular distributions for large principal quantum numbers (n10). The corresponding spherical multipole expansion contains contributions from high-order multipoles βk at least up to k8 and large values of low-order multipoles β2 well beyond the limit for dipole-allowed transitions. Comparison with recent data for ion-solid collisions shows surprisingly good agreement.
