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.
Using the SGII laser facility in Shanghai (8 laser beams, ps to ns time duration up to 16KJ energy) we discuss results on highly compressed and hot CD2 targets and explore the possibility of measuring reaction rates in such conditions. Last week results at SGII-up, using 8 ns +1 ps lasers, will be briefly addressed.
