In the helium-electron scattering, the Fano parameter gives the ratio of this type of scattering to background scattering.
In the helium-electron scattering, the Fano parameter gives the ratio of this type of scattering to background scattering. The BreitWigner distribution characterizes the differential cross section in scattering that produces these states. In electron-positron annihilation, there exists one of these phenomena corresponding to the J/psi meson at about 3.1 GeV. In that context, this word refers to large jumps in scattering cross sections due to intermediate particle states and has a width equal to have the intermediate's lifetime. In another context, a high (*) Q factor corresponds to a much smaller width of this phenomenon, and in LC circuits, one over the square root of the impedance times the capacitance is the angular frequency at which this phenomenon occurs. For 10 points, name this phenomenon in which a system oscillates with a higher amplitude at certain driving frequencies, responsible for shattering glass.
