We study evolution of timed symmetric N-atom state prepared by conditional absorption of a single photon and exhibiting superradiant decay. We find analytical expression for the initial decay rate of the state valid for any size of spherical atomic cloud. We show that the timed symmetric state is only approximately an eigenstate of the system for a large atomic cloud even if virtual processes are neglected. 2009 Elsevier B.V. All rights reserved.
