Abstract
We described the nuclear excitation at electron transition (NEET),
induced by x-rays, on the basis of strict collision theory. All
stages of the process are considered, including formation of the
hole in the
electronic K-shell, its decay accompanied by
excitation of the nucleus, filling of the M-vacancy and subsequent
deexcitation of the nucleus. The cross sections for the NEET and
photoabsorption of x-rays near K-edge are calculated. The results
agree with the data of Kishimoto et al.
