| Abstract: | The formation of a high-energy (～35 keV) beam of negative hydrogen ions was observed in the expanding femtosecond laser plasma produced at the surface of a solid target by radiation with an intensity of up to 2× 1016 W/cm2. The energy spectra of the H+ and H?-ions show a high degree of correlation. |
