Generalized oscillator strengths for some higher valenceshell excitations of argon
Abstract
The valence shell excitations of argon were investigated by an angleresolved fastelectron energyloss spectrometer at an incident electron energy of 2500 eV, and the transition multipolarities for the excitations of 3p{yields}3d, 4d, 5s, and 5p were elucidated with the help of the calculated intermediate coupling coefficients using the COWAN code. The generalized oscillator strengths for the excitations to 3p{sup 5}(3d,3d{sup '}), 3p{sup 5}(5p,5p{sup '}), and 3p{sup 5}(5s,4d) were measured, and the profiles of these generalized oscillator strength were analyzed. Furthermore, although the present experimental positions of the maxima for the electricmonopole and electricquadrupole excitations in 3p{yields}5p are in agreement with the theoretical calculations [Amusia et al., Phys. Rev. A 67, 022703 (2003)], the generalized oscillator strength profiles show obvious differences. In addition, the experimental generalized oscillator strength ratios for the electricoctupole transitions in 3p{yields}3d are different from the theoretical prediction calculated by the COWAN code.

Generalized oscillator strengths for the valenceshell excitations of neon
The generalized oscillator strengths for the valenceshell excitations to 2p{sup 5}3s, 2p{sup 5}3p, and 2p{sup 5}4s of neon were measured with an angleresolved fastelectron energyloss spectrometer at an incident electron energy of 2500 eV. The transition multipolarities for these excitations were elucidated with the help of the calculated intermediatecoupling coefficients using the COWAN code. The generalized oscillator strength profiles for the electric monopole, electric dipole, and electric quadrupole excitations were analyzed and their positions of the extrema were obtained.

Generalized oscillator strengths and integral cross sections for the valenceshell excitations of oxygen studied by fast electron impact
The generalized oscillator strengths and differential cross sections for electronimpact excitation of the A{sup '} {sup 3}{Delta}{sub u}, SchumannRunge continuum, and E {sup 3}{Sigma}{sub u}{sup }({nu}{sup '}=0,1) states of oxygen have been determined at an incident electron energy of 2.5 keV. Good agreement is found between the present generalized oscillator strengths of the SchumannRunge continuum and E {sup 3}{Sigma}{sub u}{sup }({nu}{sup '}=1) states and the previous ones measured at higher impact energies, which indicates that the first Born approximation is satisfied at an impact energy of 400 eV. However, the large difference between the present generalized oscillator strengths of themore » 
Generalized oscillator strengths for openshell and closedshell atoms
A formula, which is a useful improvement over existing ones, has been obtained to calculate the generalized oscillator strengths (GOS's) for the discrete transitions of both openshell and closedshell atoms. We illustrate our formula by calculating the GOS for the oxygen 2p{sup 4}({sup 3}P)2p{sup 3}({sup 4}S)3s({sup 3}S) transition and obtain overall good agreement with the experimental data. Our calculated GOS reveals a minimum at around the momentum transfer, K=1.26 a.u. We recommend a careful experimental search for the position of the minimum around the predicted value for confirmation.

The differential scattering cross sections and the generalized oscillator strengths of the 1{sup 1}{ital S}{r_arrow}2{sup 1}{ital S} and 1{sup 1}{ital S}{r_arrow}2{sup 1}{ital P} transitions of helium have been measured by angleresolved electronenergyloss spectroscopy with an incident electron energy of 1500 eV and within the range 2{degree}{endash}11.5{degree} of scattering angles.
