Bohr’s correspondence principle and x-ray generation by laser-stimulated electron-ion recombination

Abstract

Considering Bohr's correspondence principle and energy conservation laws, we derive by means of some elementary classical considerations of electron motion in a laser field an expression for the width of the laser-stimulated x-ray spectrum in electron-ion recombination and we find a classical expression for the power distribution of x-ray radiation, both of which agree surprisingly well with the results of the corresponding quantum-mechanical calculations presented earlier.
