A process is described for the simultaneous removal of H2S and ammonia from gaseous streams containing other acid and basic gases. The process comprises closed loop scrubbing of the gaseous stream… (More)

Photoexcitation and photoionization processes are examined for ground and excited terms of Fe I, Fe II, Fe III and Fe IV. An LS coupling R-matrix approach is used in a seventeen target term expansion… (More)

The 19-state and the 29-state R-matrix calculations have been employed to obtain the differential cross section and electron-photon coincidence parameters lambda and mod chi mod for the 11S-33P… (More)

A previously reported 29-state R-matrix electron scattering calculation including the n [le] 5 states of neutral helium is extended to include higher-incident electron energies and also (N +… (More)

An R-matrix LS-coupling calculation of the photoionization of neutral iron is presented, in which the 17 terms with configurations 3d7, 3d5(6S)4s2, 3d6(5D)4s and 3d6(5D)4p are included in the Fe+… (More)

The 19-state and the 29-state R-matrix calculations have been employed to obtain the differential cross sections for the 11S-33,1S excitation of helium. The results of the calculation reported in… (More)

The R-matrix method has been employed to study the electron excitation of atomic helium. Twenty-nine target states (n=1, 2, 3, 4 and 5) have been included in the expansion of the total wavefunction.… (More)

The 19-state and the 29-state R-matrix calculations are employed to obtain the differential cross sections for the 11S-n3,1S (n=2, 3 and 4) excitation of helium at carefully chosen non-resonance… (More)
