A composite ab initio energy surface is obtained for the HeH2 triatomic molecular system by combining earlier calculations that covered parts of the surface. The extended surface covers the full angular range of He relative to the H–H axis as well

Ab initio cross sections have been calculated for electronic excitation resulting from single collisions in the keV energy range between ${\mathrm{H}}_{2}^{+}$ initially in the ground electronic and vibrational state incident on He targets. These col

The energy surfaces of the three lowest adiabatic states of the (HeH2)+ triatomic molecular system have been calculated ab initio as functions of all three variables describing the triatomic geometry, using the BRLJHU set of quantum chemistry program

A computational method is described for obtaining inner-shell-vacancy states of three-electron atoms which combines a block-diagonalization procedure with generalized Feshbach projection operators applicable to systems with three or more electrons. T

Absolute differential cross sections have been measured for H/sup -/ formation in single collisions of H/sup +/ on Mg in the energy range from 0.5 to 5.0 keV. Total cross sections, obtained by direct integration of these differential cross sections,

Recent measurements of vibrorotational excitation in low-keV-energyLi/sup +/+D/sub 2/ collisions have shown a breakdown in arather general scaling law for projectile energy loss in the quasielasticchannel. This scaling law maintains that in small-ang
