Abstract
Longitudinal and transverse response functions are calculated for pion electroproduction from nuclei near threshold, for an experimental situation in which only the final electron is detected. For the case of calcium, a Fermi gas model is used, and the calculated response functions and cross sections are at least an order of magnitude smaller than the measured quasielastic contributions, indicating that electroproduction is a relatively unimportant background. For the case of oxygen, it is found that pion electroproduction accompanied by excitation of collective GDR states differs in magnitude and spectrum shape from that predicted by a quasifree model.
