Photodecay of a Negative Ion Exposed to Ultrashort Electromagnetic Pulses of Different Shapes
- 27 Downloads
Dependences of photodecay of a negative ion exposed to ultrashort electromagnetic pulses on pulse duration and its carrier frequency (for a Gaussian envelope) are theoretically investigated, and the energy spectrum of emitted photoelectrons is analyzed. Calculation is performed within the framework of the perturbation theory for ultrashort pulses of various shapes.
