We have performed measurements of scintillation light in liquid neon, observing a signal yield in our detector as high as (3.5 +/- 0.04) photoelectrons/keV. We measure pulse shape discrimination between electronic and nuclear recoils in liquid neon between 50 and 300 keV recoil energy. We also measure the light yield in liquid neon between 30 and 370 keV recoil energy, observing it to be 0.2 to 0.25 above 50 keV recoil energy. We also observe a dependence of the scintillation time distribution and signal yield on the pressure and temperature of the liquid neon.
