  The distortion of the energy spectrum of recoil electrons in SuperKamiokande
resulting from several solar magnetic field profiles that are consistent with
data and standard solar models is investigated. The aim is to provide a test of
the general common features of these field profiles derived in a previous work
on the basis of the resonant spin flip flavour mechanism. It is found that the
distortion may be visible in the data, becoming possibly clearer when the
energy threshold succeeds in being reduced and distinct from the ones resulting
from oscillations.
