ABSTRACT

Wereanalyze the low-energy cross section measurements of Engstler et al. using recentlymeasured energy loss data for proton and deuteron beams in a helium gas.Although the new astrophysical S-factors are significantly lower than thosereported by Engstler et al., they clearly show the presence of electronscreening effects. From the new astrophysical S-factors we find an electronscreening energy in agreement with the adiabatic limit.
