Edvardsson, P. Baltzer, L. Karlsson, B. Wannberg, D.M.P. Holland, D.A. Shaw, E.E. Rennie Title: A photoabsorption, photodissociation and photoelectron spectroscopy study of NH3 and ND3 Journal/Source: J. Phys. B: At. Mol. Opt. Phys., 32, 2583-2609, (1999); doi:10.1088/0953-4075/32/11/309 Data: table, diagram Energy/Wavelength range: ~ 10 - 25 eV (~ 49.6 - 123.9 nm) Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: The absolute photoabsorption, photoionization and photodissociation cross sections and the photoionization quantum efficiency of ammonia and deuterated ammonia have been measured from the ionization threshold to 25 eV. New structure has been observed for ND3 in the 10.0-11.3 eV range. Author to whom correspondence should be addressed: (e-mail address):
