Magnetic-dipole transitions observed in highly ionized Ga, Ge, As, and Kr

Abstract

The Texas Experimental Tokamak (TEXT) was used to observe magnetic-dipole radiation arising from transitions within the $3{s}^{2}3{p}^{n}$ ground-state configurations of highly stripped ions heavier than Ni. This device generates a plasma of 3 \ifmmode\times\else\texttimes\fi{} ${10}^{13}$${\ensuremath{-}\mathrm{c}\mathrm{m}}^{\ensuremath{-}3}$ electron density and \ensuremath{\sim}1.5-keV temperature, ideally suited for ionization of these atoms to the $n=3$ shell. Wavelength and transition-rate predictions were made with Scaled Hartree-Fock radial energy integrals.
