  Employing hamiltonians defined by two-body embedded Gaussian orthogonal
ensemble of random matrices(EGOE(2)) plus a mean-field producing one-body part,
strength functions (for states defined by the one-body part) are constructed
for various values of the strength of the chaos generating two-body part.
Numerical calculations for six and seven fermion systems clearly demonstrate
Breit-Wigner to Gaussian transition, in the chaotic domain, in strength
functions as found earlier in nuclear shell model and Lipkin-Meshkov-Glick
model calculations.
