Solar neutrino physics.

(GALLEX experiment, CERN Geneva, Switzerland 1986-1988).

Together with a colleague (prof. D. Vignaud, Saclay) from the BEBC (anti)neutrino-Deuterium experiment,

feasibility studies (by means of detector simulations) were performed for the GALLEX

experiment with respect to the detection of low-energetic (anti)neutrino interactions.

The goal was to devise a detector capable of detecting the solar neutrinos produced by

the so-called p-cycle, such that the neutrino flux close to the peak in the

solar neutrino spectrum could be measured, resulting in an improved measurement of

the absolute solar neutrino flux.

This would then form the basis for a study concerning the existing discrepancy between

the theoretical and experimental solar neutrino flux. In case of a persistent discrepancy,

the measurements could provide hints at a possible neutrino mass (difference) in case

the data is interpreted within the framework of a neutrino oscillation model.
