The reaction 13C(alpha,n)16O: a background for the observation of geo-neutrinos

Abstract

The absolute cross section of the ${}^{13}$C($\alpha$,n)${}^{16}$O reaction has been measured at E${}_{\alpha }$ = 0.8 to 8.0 MeV with an overall accuracy of 4%. The precision is needed to subtract reliably a background in the observation of geo-neutrinos, e.g. in the KamLAND detector.
