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

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