✦ Synopsis

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