Kβ x-ray transition energies of M-shell-ionized ions of Ti through Ni in a plasma
Abstract
Kβ x-ray lines from partially M-shell-ionized ions of titanium through nickel which are produced in vacuum-spark plasmas have been observed systematically for the first time, using a high-resolution curved-crystal spectrometer. Each Kβ line is clearly separated into its corresponding charge state. As a result, it is possible to measure the Kβ-type transition energies of the M-shell-ionized ions. The transition energies accurately determined are compared with those calculated for iron ions, and the agreement is excellent except for ions having some additional 3d outer-shell electrons or 3s inner-shell vacancies. The square root of the Kβ transition frequency is expressed as a linear function of the nuclear charge for isoelectronic sequences. The effective nuclear charges have been also determined for each Kβ transition. The 3p electrons do not affect the effective nuclear charges.
