  The potential for using slow-fluor liquid scintillators to study low energy
solar neutrinos and neutrinoless double beta decay (0nbb) is explored through a
series of simulations. The fluorescence model assumed for the primary fluor has
characteristics similar to acenaphthene, recently used to demonstrate Cherenkov
separation at energies around 1 MeV. Results here indicate notably better
directional reconstruction in large-scale detectors than has previously been
suggested by other approaches, allowing better identification of low energy
solar neutrinos. These studies indicate that a detector with as little as ~30%
coverage using currently available photomultiplier tubes could be able to make
a measurement of the CNO solar neutrino flux to a precision of better than 10%
(enough to distinguish metallicity models) with a few kiloton-years of
exposure. In terms of 0nbb studies here suggest that the ability to separate
mechanisms based on angular distributions is weak, but that the rejection of
solar neutrino backgrounds with such a technique might potentially approach a
factor of 10 for endpoint energies near 2.5 MeV in the angular hemisphere
defined by the solar direction.
