Influence of simultaneous static and time dependent quadrupole interactions on gamma-gamma angular correlations
We derive the forro of the perturbation factors for the angular correlation of two successive Y rays when the intermediate state is under the influence of an axially symmetric static electric field gradient plus a small randomly fluctuating quadrupole perturbation. The Bloch-Wangness-Redfield theory...

| Sumario: | We derive the forro of the perturbation factors for the angular correlation of two successive Y rays when the intermediate state is under the influence of an axially symmetric static electric field gradient plus a small randomly fluctuating quadrupole perturbation. The Bloch-Wangness-Redfield theory of nuclear relaxation is applied to calculate the evolution of the density matrix, and the form of the perturbation factors is calculated for severa! special cases in single-crystal and powder sources. |
