The dynamical theory of coherent excitation of X-ray cascade by synchr
otron radiation is developed. Fine structure of the angular distributi
on for the last quantum in the cascade (versus the incidence angle of
SR beam) is investigated. It is shown that the corresponding angular d
istribution differs essentially from the case of Mossbauer cascade and
from the conventional case of X-ray diffraction. The perspectives of
an experimental observation of the mentioned angular distributions are
discussed, The calculation results related to the two-transition X-ra
y cascade (with tungsten as a possible candidate for the experiment) f
or thick samples are presented.
