Cross section of 3He(3He,2p)4He measured near the Gamow peak Original Research Article

We measured the cross section of 3He(3He,2p)4He in the energy region of 30–50 keV center of mass energy by using the OCEAN facility. The resulting astrophysical S-factors are in agreement with the existing data and their total errors are as good as those of the previous experiment. For further study we tried the measurements at lower energies than Ecm = 30 keV. It will require running times of one month with more improvements such as background reduction and steady operation of the detection system.
