The statistical description of oscillator strengths for systems like hydrogen in a magnetic field is developed by using the supermatrix nonlinear v-model. The correlator ofoscillator strengths is found to have a universal parametric and frequency dependence, and itsanalytical expression is given. This universal expression applies to quantum chaotic systems withthe same generality as Wigner-Dyson statistics.
