RESUMO
This paper explores the production of (13)N 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 2.7-3.1kJ and initial pressure of 200-700Pa, with three or five shots in each experiment, was performed. A HPGe detector was used for gamma spectroscopy, and 511keV photons emitted by positron annihilation were utilized to measure the (13)N radioactivity. The highest activity of (13)N in these experiments was 14Bq which was acquired after five shots at a pressure of 450Pa and a 3.1kJ stored energy. Calculations based on thick target yield showed that at least 1.9×10(9) deuterons with energies higher than 330keV were ejected from the pinch region.
