| Popis: | Electron paramagnetic resonance (EPR) and optical absorption data on the negative and neutral vacancy in diamond are presented. We determine directly the constant of proportionality between the concentration of V- and the integrated intensity of its zero-phonon line (ND1). Using the standard notation, the calculated value is f(ND1) = 4.8(2) x 10(-16) meV cm(2). This differs significantly from previous accepted results which used indirect methods of calculation. Using this new number we calculate a creation rate of 0.50(5) cm(-1) for 1.9 MeV electrons at room temperature - a factor of nearly seven greater than was previously thought.
