Abstract

As the result of a recently reported experiment, a search has been made for deuterons from the reaction ${}^{3}{He} + {}^{3}{He} \to α + d + e^{+} + ν$ . Two independent experiments were done at $E_{He} = 15 and 25$ MeV. In both cases, upper limits were obtained which are about a factor of 20 below the previously measured cross section (3.4 nb/MeV sr).
