Magnetic-dipole wavelength measurements in the<i>n=3</i>configurations of highly ionized Cu, Zn, Ga, As, Kr, and Y

Abstract

Magnetic dipole (M1) transitions between the levels of the ground configurations in the 3${s}^{2}$3${p}^{x}$ Al-like through Cl-like and the 3s3p Mg-like isoelectronic sequences of Cu, Zn, Ga, As, Kr, and Y have been observed. These elements were introduced into the Texas experimental Tokomak plasma by laser ablation of metallic thin films and gas puffing. The spectral lines were recorded by using three monochromators with photoelectric detection and a spectrometer with a channel electron multiplier array detector. Twenty-eight newly observed M1 lines were measured and classified.
