Abstract
The process of atomic ionization by intense electromagnetic field is still the subject of active investigations. Three aspects of this process have recently attracted attention. The first is the progressive loss of the multiphoton character as the field becomes progressively stronger. The second is related to the trapping of population in excited states during transient resonances. The third concerns the process of multiple electron ejection.
