This paper explores the production of ¹³N by bombardment of a carbon target by high energy deuterons in a medium energy plasma focus. A set of experiments in the energy range of 2.7-3.1 kJ and initial pressure of 200-700 Pa, with three or five shots in each experiment, was performed. A HPGe detector was used for gamma spectroscopy, and 511 keV photons emitted by positron annihilation were utilized to measure the ¹³N radioactivity. The highest activity of ¹³N in these experiments was 14 Bq which was acquired after five shots at a pressure of 450 Pa and a 3.1 kJ stored energy. Calculations based on thick target yield showed that at least 1.9¡Á10⁹ deuterons with energies higher than 330 keV were ejected from the pinch region.
