Аннотация: A new approach is proposed to the production of high-energy ions from a cluster jet irradiated with relativistic (5·1018 W/cm2) femtosecond laser pulses, based on the formation of mixed clusters with an Xe core surrounded by a Kr shell. The appearance of distinguished charge states of accelerated ions was registered: instead of low-charge Kr2+, Kr3+, Kr4+, Kr5+ for pure Kr clusters, there are three components Kr8+, Kr14+, Kr20+ for mixed KrXe clusters. The energy range of detected ions expands significantly: from 1-6 MeV for Kr clusters to 2-16 MeV for KrXe clusters. Keywords: femtosecond laser pulses, relativistic intensity, ion acceleration, mixed clusters, Kr, Xe. DOI: 10.61011/EOS.2023.02.55788.12-23
