摘要Electron energy loss spectra of inner-shell excitations of 2p electrons of argon are measured at an incident electron energy of 2500 eV and scattering angles of 0° and 4°. The dipole−forbidden transitions of 2p3/2-14p and 2p3/2-15p are observed in the measured spectra and assigned based on the calculations of the Cowan code. The positions and line widths for the excitations of 2p3/2-1nl and 2p1/2-1nl(n≤5) of argon are determined. The present results show that the line widths of the electric quadrupole transitions of 2p3/2-14p[5/2+3/2]2 and the electric monopole one of 2p3/2-14p[1/2]0 are less than those of the dipole-allowed transitions.
