T: 298K
λ: 20.7-124nm(e,e)
BIBLIOGRAPHY: G.R. Wight, M.J. Van der Wiel, and C.E. Brion, "Dipole oscillator strengths for excitation, ionisation and fragmentation of NH3 in the 5 to 60 eV region", J. Phys. B: Atom. Mol. Phys. 10, 1863-1873 (1977); DOI: 10.1088/0022-3700/10/10/016
COMMENTS: Measured by dipole (e,e) spectroscopy; energies E (in eV) and differential oscillator strengths df/dE (in 10-2 eV-1) converted to wavelengths and absorption cross sections,
σ (in 10-18 cm2 molecule-1) = 109.75 df/dE (in eV-1)
