Classification of Be i-like and B i-like iron and vanadium spectra from laser-produced plasmas

Be i-like spectra of V xx and Fe xxiii and B i-like spectra of Fe xxii are classified as a result of spectroscopic observations of the plasmas formed by focusing the output of a neodymium glass laser onto plane solid targets. Wavelength measurements published by the Lebedev Institute, Moscow, were also used, for the iron spectra. The analysis was undertaken with the help of theoretical calculations of atomic energy levels and oscillator strengths.
