Notes:
We have derived exact analytical expressions for the diagonal matrix elements 〈n|xk|n〉, k = 1, 2, for the Morse oscillator using the operator algebra of the two-dimensional harmonic oscillator and the method of the parameter differentiation. These expressions avoid the roundoff error present in other relations. The method can be extended to other integrals where k 〉 2.
