Photoionization experiments of ammonia have been performed by synchrotron radiation vacuum ultraviolet light source in U10A,NSRL.Photoionization efficiency curves of H+,NH2+and NH3+from NH3 were measured, and appearance potentials of H+ and NH2+ were 18.57±0.05eV, 15.77±0. 02 eV respectively and the ionization potential of NH3 was 10. 22±0. 02 eV. The N─H bond dissociation energy D0(H2N H)=4. 97±0.05 eV as well as the dissociation energy D0(H2N+ H)=5.55±0.02 eV was determined from the data.
