Abstract

Using a fully quantum mechanical treatment, cross sections have been calculated over a wide range of center-of-mass collisionenergies ( 0.1 – 10 000 eV ) for the elasticscattering of protons from noble gas atoms He, Ne, Ar, Kr, and Xe. In addition, the momentum transfer and viscosity cross sections, relevant to transport modeling, have been computed along with results of the classical trajectory Monte Carlo method. The comparison of the results from two methods of calculation enables improved insight into the accuracy of the cross sections obtained within various energy ranges. Scaling relations of fusionenergy research interest are given allowing the data to be applied for D + and T + impact. Also, owing to improvements and extensions of the methods utilized here, we describe updated elastic and transport cross sections for H + + C in the Appendix. All of the data calculated here are explicitly tabulated on the worldwide web for convenient use in plasma modeling.
