| الوصف: | The development of buffer-gas trapping and magnetized beam formation has provided positron beams with significantly improved energy resolution (ΔE≤0.025 eV) compared to those available previously. Analysis techniques havebeen developed to take advantage of the fact that the beam is in a magnetic field of ∼0.1 T. This has enabled scattering experiments at lower energies and with significantly improved state selectivity for excitation experiments than had been possible previously. A detailed description of these techniques is presented. Data are presented for a variety of cross sections for scattering of positrons from atomic and molecular targets. |
