An electron bunch circulating in a storage ring constitutes a dynamical system with both longitudinal and transverse degrees of freedom. Through a self-interaction with the wakefields created by the bunch, certain of these degrees may get excited, de

We report on high resolution measurements of resonances in the spectrum of coherent synchrotron radiation (CSR) at the Canadian Light Source (CLS). The resonances permeate the spectrum at wavenumber intervals of $0.074 ~\textrm{cm}^{-1}$, and are hig

Recent estimates of the p-wave multipoles for p(\ensuremath{\gamma},${\mathrm{\ensuremath{\pi}}}^{0}$) near threshold [J. C. Bergstrom, Phys. Rev. C 50, 2979 (1994)] are compared with new low-energy theorems (LETs) derived from heavy-baryon chiral pe
