Study of ultrafast processes in matter by means of time-resolved electron diffraction and microscopy

One of the most fundamental problems of modern natural science is the direct observation of atomic motions in the course of various processes. For this purpose, in the experiment it is necessary to provide high spatial-temporal resolution. The solution to this problem is achieved by using a pulsed e...
