Acceleration of quasi-monochromatic electron beams in laser wakefield to 300 Mev and initiation of photonuclear reactions

We observed quasi-monoenergetic electron beams with energy up to 300 MeV from the laser wakefield. The resultant electron beams have been used to perform efficiently gamma-neutron activation of
¹²
C and
⁶³
Cu and photo-fission of
²³⁸
U.
