The hydroxyl radical, OH, is an important component of many natural and technological plasmas but there is little available information on processes involving its collisions with low-energy electrons. Low energy electron collisions with OH are studied in the framework of the R-matrix method. Potential energy curves of some of the low lying target states of doublet and quartet symmetry which go to the O(P-3)+ H(S-2), O(D-1)+ H(S-2) and O(S-1)+ H(S-2) asymptotic limits are obtained for internuclear separations between 1 and 6 a(0). Scattering calculations are performed at the OH equilibrium geometry R-e = 1.8342 a(0) to yield cross sections for elastic scattering, electronic excitations from the X (2)Pi ground state to the first three excited states of A (2)Sigma(+), a (4)Sigma(-), 1 (2)Sigma(-) symmetry and for electron impact dissociation of OH. The positions and widths for negative ion resonances in the e-OH system are used to estimate the cross section for dissociative electron attachment to OH which is found to be significant at electron energies about 1.5 eV.<\/p>\n","protected":false},"excerpt":{"rendered":"
