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