The exciton L=0 and L=1 states of a spherical GaAs quantum dot with a Gaussian confining potentialare calculated by using the matrix diagonalization method.The size dependence of the exeiton levels and the influence ofthe depth of the confining potential well in the spherical quantum dots are investigated.The same calculations performedwith the parabolic approximation of the Gaussian potential lead to the results,which are qualitatively and quantitativelydifferent.
