Resonances in coupled channels in nuclear and particle physics
Abstract Starting from first principles this report gives account of the important latest developments on resonances in coupled channels in nuclear and hadronic physics. It also gives many new results which have remained hitherto unpublished. All types of poles of the S matrix are considered in coupled-channel problems, on all Riemann sheets.

This paper reports several results from the corresponding presentation given by the author at the IFAE 2016 conference in Genova. Because of the large number of studies reported there and the limited space available for these proceedings, only a small fraction of the results will be cited here.

Physical structure, optical resonance, and surface-enhanced Raman scattering of silver-island films on suspended polymer latex particles [PDF]
A new approach to producing SERS activity on dispersed particles is described. Silver islands are deposited onto submicron latex and glass particles, and the particles are dispersed into aqueous suspensions. The physical structure of the metal islands is investigated by transmission electron and atomic force microscopies and compared with the optical ...

Physical mechanism of wave-particle resonances in a curved magnetic field
The Physics of Fluids, 1982The physical mechanism of wave-particle resonances in a curved magnetic field is investigated. Specifically, the energy exchange process between a wave and resonant curvature drifting particles is discussed (i.e., ω∼k⋅Vc, where Vc = v2∥/RcΩ is the curvature drift, Rc is the radius of curvature of the magnetic field, and Ω is the cyclotron frequency). A

Physical mechanism of wave-particle resonances in an inhomogeneous magnetic field. I. Linear theory
The Physics of Fluids, 1981A physical description is given of the wave-particle resonance which can occur when particles undergoing a ∇ B drift are in phase with a wave propagating across the magnetic field (i.e., ω ∼ k⋅V∇ B, where V∇ B is the ∇ B drift velocity). Specifically, the physics of the energy exchange mechanism is discussed and a general equation for the wave damping ...
