TDPAD studies on19F implanted into diamond

Abstract

19F has been used to probe the electric field gradients in the diamond lattice. The measurements were performed via the time differential perturbed angular distribution (TDPAD) technique applied to the 197 keV state (τ=128 ns, Q=0.10 b) of19F. The nuclei were excited and recoil implanted into the diamond crystal using a (p,p′γ)-reaction initiated by a pulsed 4 MeV proton beam. Spin rotation spectra were generated to study the dependence of the electric field gradients on the orientation of the crystal planes, the diamond type, and temperature.
