Abstract

The paramagnetic centers and their nature in nanocrystalline B4C particles have been comparatively studied before and after neutron irradiation. Electron Paramagnetic Resonance (EPR) spectroscopic analyses were conducted in the magnetic field range of 0.05-0.55 T (500-5500 Gauss). Furthermore, the region of 0.3270-0.3370 T, where more paramagnetic centers were observed, was specifically examined. The nature of newly formed paramagnetic centers due to the influence of neutron irradiation in B4C nanocrystalline particles has been elucidated through EPR spectra. The mechanism of VB and VC vacancy formation has been thoroughly investigated through neutron transmutation.
