Status and New Data of the Geochemical Determination of the pp-Neutrino Flux by LOREX

Estimate of the present amount of in lorandite due to solar neutrinos and to background reactions in the last years as a function of the paleodepth of lorandite. The values are calculated by Pejović by adopting the value of for the neutrino capture cross-section for from Hartman et al. [9], the contents of U and Th in lorandite and surrounding rocks are from Pavićević [6] and the method of Heisinger et al. [7]. : contributions due to lead mobilized from the rock walls. : contributions from natural radioactivity. : contribution due to reactions induced by fast cosmic muons. : number of due to solar neutrino capture, for a capture rate of 146 SNU , obtained after correcting the original 260 SNU value for neutrino flavour-oscillations. : the sum of the neutrino contribution and of all background contributions.
