We present a supersymmetric analysis for the d-dimensional Schrodinger equation with the generalized isotonic nonlinear-oscillator potential V (r) = B(2)/r(2)+omega(2)r(2)+ 2g(r(2) - a(2))/(r(2) + a(2))(2), B >= 0. We show that the eigenequation for this potential is exactly solvable provided g = 2 and (omega a(2))(2) = B(2) + (l + (d - 2)/2)(2). Under these conditions, we obtain explicit formulae for all the energies and normalized bound-state wavefunctions.
