摘要/Abstract

摘要： We provide systematic calculations about the energy levels, Einstein coefficients and oscillator strengths for electric quadrupole (E2) and magnetic quadrupole (M2) transitions between n=3 and n=2 of Ne-like systems by using the fully relativistic multi-configuration Dirac-Fock method. The oscillator strengths of the E2 transitions under Coulomb and Babshkin gauges are compared with each other and show the differences from 1.2 to 12 percent. We also found that the M2 line (0.37429 nm) with the biggest oscillator strengths in Ne-like Ag³⁷⁺ mixes with the line (2p⁵_3/23s_1/23d_5/2)_3/2→gs (0.37427 nm) emitted by the Na-like Ag³⁶⁺.
