Abstract
A simple variational study of the ground-state properties of an electr on-hole system confined to a quantum box is presented. A two-parameter trial wavefunction which is asymmetric with respect to the coordinate s of the two particles is introduced to account for both the localizat ion of the heavy particle and the correlation between the two particle s. The mass dependence of the ground-state energy and the average part icle separation is discussed.
