We have observed deuterons accelerated to energies of about 2 MeV in the in
teraction of relativistically intense 10 TW, 400 fs laser pulse with a thin
layer of deuterated polystyrene deposited on Mylar film. These high-energy
deuterons were directed to the boron sample, where they produced similar t
o 10(5) atoms of positron active isotope C-11 from the reaction B-10(d,n)C-
11. The activation results suggest that deuterons were accelerated from the
front surface of the target. (C) 2001 American Institute of Physics.
