Abstract
The cross section of the reactions (3) He(d, p)(4) He and d((3) He, p)He-4 has been measured at the center-of-mass energies E = 5 to 60 keV and 10 to 40 keV, respectively. The experiments were performed to determine the magni tude of the electron screening effect leading to the respective electron-sc reening potential energy U-e = 219 +/-7 and 109 +/-9 eV, which are both sig nificantly higher than the respective values from atomic physics models, U- e = 120 and 65 eV.
