Abstract / Description of output

The stopping power of atomic and molecular deuterons in He-3 gas was measured over the range E-d = 10 to 100 keV using the He-3 pressure dependence of the He-3(d,p)He-4 reaction yield. At energies above 30 keV, the observed stopping power values are in good agreement with a standard compilation. However, near 18 keV the experimental values drop by a factor 50 below the extrapolated values of the compilation. In a simple model, the behavior is due to the minimum 1s --> 2s electron excitation of the He target atoms (= 19.8 eV, corresponding to E-d = 18.2 keV), i.e. it is a quantum effect, by which the atoms become nearly transparent for the ions.
