Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Using spin-asymmetry data from electron-impact-ionization studies of H, He*, Li, Na, K, and Cs, we determine the energies at which dynamical influences on the inside part of the final-state wave function create detectable departures from the simple Wannier power-law dependence of the cross section on escape energy for the singlet and triplet channels separately. From a comparison of these energies for the six valence-1 systems examined, we conclude that asymmetry measurements provide a window for observing the effects of screening and core polarization on the dynamics of the highly correlated Coulomb three-body breakup. © 1993 The American Physical Society.
