Abstract
We have found an unexpectedly large number (2.8 × 1018/cc) of electronic paramagnetic centres in microspheres of fluorocarbon. These centres are peroxy-radicals. We have used them to produce for the first time a dynamic polarization of He3 adsorbed on the surface of the particles. However the origin of the coupling between He3 and fluorine nuclei observed in this system is not yet understoodKeywords
