Abstract

MeV negative oxygen ions are obtained from a water spray target irradiated by high intensity (5 x 10(19) W/cm(2)) and ultrashort (50 fs) laser pulses. Generation of negative ions is ascribed to electron-capture processes that the laser-accelerated high-energy positive ion experiences when it interacts with atoms in the spray. This mechanism implies the existence of a large number of MeV neutral oxygen atoms, which is consistent with indirect experimental evidence. (C) 2011 American Institute of Physics.
