Comments: The absolute photoionization cross section of the amino radical has been measured in the present work for the first time at two photon 
energies: sigma(ion)NH2(12.7 eV) = 7.8 ± 2.2 Mb and sigma(ion)NH2(13.2 eV) = 7.8 ± 2.0 Mb. These values have been employed to scale the total ion 
yield previously recorded by Gibson et al. (J. Chem. Phys. 1985, 83, 4319-4328).
