solar spectrum.
If the proposed MSW solution is relevant
to explain the solar
neutrino deficit, then not only the
rate of
neutrinos is affected but
the shape of the neutrino
spectrum
should be significantly distorted.
Therefore, the ICARUS goal in the solar neutrino area is not
only
to confront the Standard Solar Model (absolute event rate),
but also to provide a Solar Model
independent measurements, by observing
various independent processes differently affected by neutrino
oscillation.
ICARUS can detect solar neutrinos
by observing the electron produced in the
following two reactions:
