High-resolution n-italic = 3 to n-italic = 2 spectra of neonlike silver
Spectra of the n-italic = 3 to n-italic = 2 transitions in neonlike silver emitted from the Princeton Large Torus have been recorded with a high-resolution Bragg-crystal spectrometer. The measurements cover the wavelength region 3.3--4.1 A-circle and include the forbidden 3p-italic..-->..2p-italic electric quadrupole lines. Transitions in the adjacent sodiumlike, magnesiumlike, and aluminumlike charge states of silver have also been observed and identified. The Ly-..cap alpha.. spectra of hydrogenlike argon and iron, the K-italic..cap alpha.. spectra of heliumlike argon, potassium, manganese, and iron, and the K-italic..beta.. spectrum of heliumlike argon fall in the same wavelength region in first or second order and have been measured concurrently. These spectra provide a coherent set of wavelength reference data obtained with the same spectrometer and from the same tokamak. This set is used as a basis to compare wavelength predictions for one- and two-electron systems to each other and to determine the transition energies of the silver lines with great accuracy.
