We consider a one-electron atom in an arbitrary curved spacetime. After reviewing the generalization of the Dirac equation to curved spacetime, we develop the perturbation theory of degenerate stationary states taking into account the Hermiticity properties appropriate to curved spacetime. We then calcula...

The ratios R k1.of k-fold to single ionisation of the target atom with simultaneous oen-electron capture by the projectile have been measurd for 15–480 keV/u ( v p = 0.8–4.4 a.u.) collisions of C q+, O q+ ( q = 1–4) with Ar, using time-of-flight techniques which allowed...
multiphoton ionization and excitation to highly excited states (e.g., rydberg states)Our simple theory for excitation of Rydberg atoms by two short, weak half-cycle pulses confirms the experimental data and results of previous calculations. We show that the stronger the field, the faster are the...
