Within the effective-mass approximation a simple method to calculate the spectra of a shallowdonor impurity in GaAs±(Ga, Al)As cylindrical quantum-well wires (QWWs) suitable for any confinement potential shape in radial direction is proposed. A trial function is taken as the product of a hydrogenic
