    Forbidden singlet–singlet transitions in collisional processes (1991)

    Notes: In an atomic collision in which total spin angular momentum is conserved, retention of singlet status by either collision partner is strictly forbidden when the other collision partner undergoes a change in multiplicity. The absence of such forbidden transitions appears to be the only stringent test of spin conservation. This is strikingly manifested in the translational energy spectra of boron ions, B+, scattered off CO molecules, with suppression of the interaction channel B+(1S)+CO(X 1Σ+)→B+(1S)+CO (a 3Πrf). For projectile ions in nonsinglet ground states, the singlet–triplet X 1Σ+→a 3Πr excitation of CO is an unusually prominent feature.

    Notes: High-resolution translational energy spectroscopy is an effective means of obtaining detailed state-selective information, permitting systematic investigation of spin conservation in collisional processes. In this paper, we examine collisional excitation of one selected singlet (N2) and one non-singlet (O2) target by a variety of projectile ions, providing a kaleidoscope of assorted effects.

    Notes: Vibrational excitation of CO by N+ and O+· is investigated by means of high-resolution translational energy spectroscopy. The spectra display unusual features which are discussed in relation to the Wigner spinconservation rule. Reaction channels involving CO (X1Σ+→a3Πr) are prominently featured.

    Vibrational excitation of N2 by C+ ions (1990)
    New York, NY : Wiley-Blackwell

    Topics: Physics
    Notes: High-resolution translational energy spectroscopy (0.1 eV full width at half maximum) has been performed on 3 keV C+ ions scattered off N2 molecules. The intriguing energy loss spectrum with well-resolved vibrational structure is explained on the basis of simultaneous transitions involving changes of states in the C+ ion and the N2 molecule.

    Energy studies of atomic atmospheric ions in collisions with molecular nitrogen and oxygen (1991)

    Notes: Studies of internal energy changes between the partners in ion-molecule collisions can be facilitated by high-resolution translational energy spectroscopy. Collisions of keV H+, N+ and O+ on molecular nitrogen and oxygen have shown that for 30 reaction channels all are consistent with spin conservation, which has not been generally acknowledged in previous studies. Estimations of the fractional metastable composition in each ion beam have also been made.
