Photoelectron-enhanced plasma lines at angles with the geomagnetic field are investigated numerically and experimentally with the EISCAT UHF radar. Numerical simulations of enhanced plasma line intensities are carried out for a power law photoelectron distribution and a set of different temperatures and angles with the magnetic field. The calculations indicate that plasma line measurements may be successful at large angles even in the E region, because of the low electron temperature in this region. A filter bank power profile experiment was set up to measure upshifted and downshifted plasma line intensities as a function of angle with the field, from small to intermediate angles, and also for a fixed large angle (74¿) with the field. As predicted by the simulations, plasma lines were detected at large angles also in the E region at 120 km altitude. To study the angular variation of the plasma line intensities, the photoelectron flux was calculated from a model based on the Boltzmann transport equation with parameters describing the ionospheric conditions present during the experiment. A power law flux was fitted to the calculated data and used in the numerical calculations to model the plasma line intensities for comparison with the experimental results. When allowing for a pitch angle dependence in the flux, the plasma line temperatures can be predicted to within a very good accuracy at altitudes where remnants of the N2 excitation dip are no longer present in the photoelectron distribution. ¿ American Geophysical Union 1992
