Interaction of the attosecond pulse of the electromagnetic field with atomic anions

Using the sudden disturbance approximation, we have obtained expressions for calculating the scattering spectra of an attosecond pulse on atomic anions, taking into account the magnetic component of the electromagnetic field. It is shown that when an attosecond pulse of the Gaussian form electromagnetic field interacts with an atomic anion, the second harmonic is generated in the scattering spectrum. The paper presents analytical dependence of the partial spectrum on frequency. The obtained expressions have an analytical form, which makes it possible to carry out the most complete analysis of the systems under consideration. It is shown that scattering patterns with regard to the magnetic component of the field have characteristic quantitative and qualitative differences. In practice, this means that by detecting the scattering spectra, one can predict the form and final states of the anions.
