Abstract
Generation of fast ions in snow nanotubes irradiated by femtosecond laser pulses in the intensity range of 1016 - 1017 W cm2 was investigated. The fast ion energy was measured through x-ray emission spectra of multicharged ions of oxygen. The profile of the He-Β and Ly-α in He-like and H-like oxygen lines demonstrates a significant broadening, which may indicate generation of fast He-like and H-like ions with energies of up to 100 keV.
