Variational Calculation of Low-energy Positron Life Time in Xe Atoms
Positron Annihilation Bound wavefunction Scattered wavefunction Variational Method
2010/6/30
The least-squares variational method (LSVM) is used for determining trial wavefunctions representing lowenergy positron-xenon elastic scattering, which are used to determine the positron lifetime. The...
Low-Energy Electron Collisions with Ethane
Elastic scattering Polarization effects Ramsauer-Townsend minimum
