Abstract
The potential of the GENIUS proposal [1] to measure the
spectrum of low energy solar neutrinos in real time is studied.
The detection reaction is elastic neutrino-electron scattering
. The energy resolution for
detecting the recoil electrons is about 0.3 %, the energy threshold
is a few keV. The expected number of events for a
target of one ton of natural germanium is 3.6 events/day for
pp-neutrinos and 1.3 events/day for 7Be-neutrinos, calculated
in the standard solar model (BP98 [2]).
It should be feasible to achieve a background low enough to measure
the low energy solar neutrino spectrum.
