Abstract

Excitation of radiative transitions of dysprosium atoms from even levels belonging to 4f 96s 26p and 4f 106p 2 configurations has been studied by experiment. Sixty-six excitation cross sections measured at an exciting electron energy of 30 eV. Four optical excitation functions recorded in the electron energy range of 0−200 eV. A classification based on known DyI energy levels proposed for several spectral lines. In most cases excitation cross-sections measured do not exceed 1 × 10−18 cm2 as the parity of upper levels studied in the present paper coincide with the parity of the DyI ground level which is the initial level in the excitation process.
