Abstract

Just as phosphorus in silicon produces a hydrogenic defect, the double donor selenium in silicon is an analog of helium. We have measured the impurity absorption spectrum at high magnetic field, and we show that the odd-parity excited states of Si: Se behave identically to those of Si: P. This fact allows us to isolate the electron-electron interactions (exchange and correlation) in the ground state from the quadratic Zeeman effect. The field tuning allows us to put upper limits on the strength of some of these interactions (e. g., at 30 T the electron-electron correlation interaction in the ground state of Se is less than about 40 mu eV; at 30 T the quadratic Zeeman energy in the ground state of P is less than about 200 mu eV).
