Study of photo-proton reactions driven by bremsstrahlung radiation of high-intensity laser generated electrons

Photo-nuclear reactions were investigated using a high power table-top laser. The laser system at the University of Jena ( I 3-5◊ 10 19 W cm 2 ) produced hard bremsstrahlung photons (kT 2.9 MeV) via a laser-gas interaction which served to induce (, p) and (, n) reactions in Mg, Ti, Zn and Mo isotopes. Several (, p) decay channels were identified using nuclear activation analysis to determine their integral reaction yields.
