... 'angular' is used to describe motion in a circular path. If you are moving in a curved path, you are passing through some angle if you take the center of the path as the center of circle. Circular motion and rotational motion might seem like the same thing - and they are very similar. A familiar exa ...

... The quantity ’() gives the part of the current which is in phase with the field and which therefore leads to absorption of energy. Hence, this quantity is comparable with ’’(). The quantity ’’() gives the part of the current with a phase difference of with respect to the field. Thus, ’’() is ...

The main experimental difficulty in studying recollision in negative ions stems from the fact that neutralization will occur before the intensity of the pulse becomes sufficiently high for excitation or ionization of the core. At the wavelength used for our experiments (800 nm), the laser intensity ...
