Av. Ivanova et Bn. Provotorov, About contribution of dipole-dipole interactions to super-radiation of finite-size samples, CHEM PHYS R, 17(5), 1998, pp. 1005-1010
Dipole-dipole interactions are shown to be the factor controlling the shift
of the fundamental frequency of a super-radiation (SR) pulse with respect
to the resonance frequency and playing a crucial role in formation of the o
scillatory structure of SR pulses.
