Energy Spectrum and Charge Composition of Laser Plasma Ions

A mass spectrometric study of the spectra of multi-charged ions A1, Cu, depending on the frequency v = 1, 3, 5, 10, 12 Hz and at q = 10¹¹ W/cm². It has been proved that with increasing q of laser radiation, the energy spectrum of ions expands towards high energies, and the energy spectrum also has several maxima, the number of which increases with increasing q of laser radiation. It has been experimentally proven that silicon ions with a charge Z > 6 recorded in a plasma formed from a γ-irradiated target under study are characterized by a lower minimum energy than an unirradiated target.
