Phys. Rev. 165, 1579. 12 The quoted ranges include values of A T and A LS from Refs. 8, 10, and 11 and R. A. Arndt, R. H. Hackman, and L. D. Roper, Phys. Rev. C 9, 555 (1974). From the latter reference we include the phase shifts from the 1-500-MeV analysis and two sets of phase shifts obtained from the analysis of the 1-27.6-MeV data.13 Arndt, Hackman, and Roper, Ref. 12. The caption of Fig. 3 is incorrect. The floated curves are the upper one for Fig. 3(a) and the lower ones for Figs. 3(b) and 3(c). The numbers on the vertical scale in Figs. 2(b) and 3(b) should be negative and the values in Fig. 3(b) should be integer multiples of 0.2 [R. A. Arndt, private communication].14
Spontaneous emission of photons by an atom placed near a dielectric cylindrical waveguide at an arbitrary position is analyzed using global free electromagnetic modes, satisfying necessary continuity conditions at the slab boundaries. These modes include the modes extended over the whole space ͑travelling͒ and the modes trapped to a waveguide ͑waveguided͒. To describe angular properties of the spontaneous emission, a parametrization of the travelling modes by the outgoing waves has been proposed. Angular characteristics of the travelling photon emission, distributions of the trapped photon emission, as well as the global decay rates have been calculated using the quantum approach and the standard perturbation theory. Difficulties due to the presence of sharp resonances ͑whispering gallery modes͒ among the travelling photons are pointed out.
The authors study the spontaneous emission of an atom described by an extended wavepacket. They show that the shape of the emitted line is affected by the Doppler shifts and carries the information of the initial wavefunction. The total intensity is found to exhibit a standard dipole pattern.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
