The decay of 16N is used to cross check the absolute energy scale calibration for solar neutrinos established by the electron linear accelerator (LINAC). A deuterium-tritium neutron generator was employed to create 16N via the (n,p) reaction on 16O in the water of the detector. This technique is isotropic and has different systematic uncertainties than the LINAC. The results from this high-statistics data sample agree with the absolute energy scale of the LINAC to better than 1%. A natural source of 16N from the capture of μ- on 16O, which is collected as a background to the solar neutrino analysis, is also discussed.
