Abstract
The binding energy and susceptibility of an off-centre neutral hydrogenic donor impurity (D0) trapped in a three-dimensional Gaussian quantum dot in the presence of an applied magnetic field are obtained by a variational method with an improved wave function. The results are obtained as a function of the quantum dot size, position of the impurity and the confinement strength.
