General theory of nuclear excitation by electron transitions A. Ya. Dzyublik
Phys. Rev. C 88, 054616 – Published 25 November 2013 ABSTRACT We described the nuclear excitation by electron transition (NEET) by using strict collision theory combined with quantum electrodynamics. All stages of the process are considered, which include ionization of the atom by an x-ray photon with the formation of the hole in an inner electronic shell, its decay accompanied by the excitation of the nucleus, and the subsequent deexcitation of the nucleus. The cross sections for the NEET and photoabsorption of x rays are calculated near the threshold. We also analyzed the fine structure of the NEET curve analogous to the extended x-ray-absorption fine structure, well known in x-ray optics. The results agree with the findings of Kishimoto et al. [Phys. Rev. C 74, 031301(R) (2006)]. http://journals.aps.org/prc/abstract/10.1103/PhysRevC.88.054616 Harry
