Systematic investigation of diabatic correlations

Charge state dependence of characteristic x-ray emission under single collision conditions for 1.4 MeV/amu Cu ions

“…Due to the high charge states of the incoming Cu projectiles the level order of the separated system depends on q. [15] seems to be appropriate for our discussion. This diagram is given in Figure 5.…”

Disparity in transient field characteristics for Au ions traversing Fe and Gd hosts through measurements ofg-factors in197Au

“…Small M-shell vacancy fractions, predominantly in the 3d orbital, were deduced for both Os and Pt, implying negligible contributions from 3 s vacancies to the observed TF strengths. Because their data suggested 3 d vacancies were predominantly created in Os and Pt ions, these authors claimed [26] that their results favoured the molecular orbital (MO) coupling rule of Lichten [27] over that of Eichler et al [28] and that, as a consequence, the vacancy-sharing mechanism proposed in [6] could not apply. However, it is not clear that these measurements [26] for the M-shell, and the apparent favouring of a particular qualitative coupling rule for that shell, can be used to draw firm conclusions about the N shell.…”

“…However, it is not clear that these measurements [26] for the M-shell, and the apparent favouring of a particular qualitative coupling rule for that shell, can be used to draw firm conclusions about the N shell. For example, the discussion of Eichler et al [28] indicates that vacancies created in the 4fo-MO may become 3s or 3d vacancies in the separated atom limit, depending on the actual shapes of the adiabatic MOs near the crossings. As such, it seems premature to dismiss, as do Pakou et al [26], the suggestion [6] that the reduced TF strengths can be accounted for by a mechanism which involves the sharing of vacancies between the ion-4s and host2p shells.…”

The liH2+ quasimolecule. a comparison between the configuration interaction and the OEDM approaches

“…Even if these rules must be modified or extended in some cases (e.g. [20] Furthermore we also show in the present work that the detailed structure of the radial and rotational coupling matrix elements in the GTO-CI expansion can be understood by using their relation with those evaluated in the OEDM expansion whereas this can usually be done only in a qualitative manner by inspection of the expansion coefficients [5][6][7][8].…”
