The half-width and separation of the components of a close high-Q doublet and the normal modes of vibration of circular rings with rectangular cross-sections

The half-width and separation of the components of a close high-Q doublet and the normal modes of vibration of circular rings with rectangular cross-sections

With axially symmetrical vibrating systems like rings, cones and bells most of the normal modes occur as degenerate doublets with the two components having equal Q values. If a slight asymmetry is introduced into the system - either structural or metallurgical - these doublets split slightly and oft...
