Abstrakt:
The plasma astrophysical S factor for the 3He(d;p)4He fusion reaction was measured for the first time at temperatures of few keV, using the interaction of intense ultrafast laser pulses with molecular deuterium clusters mixed with 3He atoms. The experiments were performed at the Petawatt laser facility, University of Texas, Austin-USA. Different proportions of D2 and 3He or CD4 and 3He were mixed in the gas target in order to allow the measurement of the cross section. The yield of 14.7 MeV protons from the 3He(d;p)4He reaction was measured in order to extract the astrophysical S factor at low energies.
Recent results obtained at the SGII-laser facility, Shanghai-China on the CD2 targets will be discussed with particular emphasis on the reached high densities.
Hydro-dynamical calculations will be presented for some experimental situations and the limits of the model will be stressed. Some simulations for possible experiments at ELIMED will also be presented.
