During this thesis, the ionization of atoms and small molecules in powerful laser fields is experimentally studied utilizing a response microscope. The inhabitants of autoionizing doubly excited states within the laser fields is confirmed and a potential connection to the well known dielectronic recombination techniques is mentioned.

THE HOTCHKISS MITRAILLEUSE. This arm entirely resembles the Revolving Cannon in its construction, but it is generally made with nine instead of five barrels, the motion of the crank being accelerated by two helical wheels, to allow a speed of fire of about r so shots per minute. impossibility of being able to supply the g un with ammunition with the necessary precision and order. The speed of I 50 rounds per minute allows the application of the simple mechanism adopted for this arm, and it is also 4I with it to be less feared that ammunition may be unnecessarily wasted, as is the case with guns firing excessively fast.
