The data show the quantal system being influenced by various resonance effects, some of whose origins are most easily found in the corresponding classical system, others of which are not. When ω ω K is near low-order rational fractions r s, r = 1,2 and s = 1,2, , the classical dynamics is strongly affected by nonlinear resonances easily.

Molecular energy transfer in the H r-H system: a quasiclassical trajectory study. by William James Keogh Download PDF EPUB FB2

Exact quantum dynamics study of the O++H2(v=0,j=0)→OH++H ion-molecule reaction and comparison with quasiclassical trajectory calculations.

The Journal Author: Raphael D. Levine. Quasiclassical trajectory calculations have been carried out for H(2)(v(1)=high)+H(2)(v(2)=low) collisions within a three degrees of freedom model where five different geometries of the colliding. Quasiclassical trajectory calculations have been carried out on a previously derived potential-energy surface for the F + l2 reaction which has a potential-energy well in the collinear Fll.

The cross-section for the reaction, O + + N 2 → NO + + N, as a function of the ion energy, has a maximum of about 4 X sq. at 10 e.v. and falls off for higher or lower ion energies.

The low energy fall-off of the cross-section explains the persistence of O + ions in the ionosphere but is a puzzling and unexpected result. Some very tentative reasons for this fall-off are suggested. Figure 2. Coordinates, transition state geometry, and potential energy surface for CHD 3 dissociation on Ni().

More recently, however, in the last 15 years, there has been much interest in overcoming these difficulties. Researchers from atomic, molecular, and optical sciences, or from mesoscopic, high-energy, and mathematical physics, have converged to study different time quantities in quantum mechanics.

To study the effect from the rotational state of H 2, two different H 2 samples were used in the experiment: normal H 2 (n-H 2) and p-H 2 [97, 98]. The H 2 molecules in the molecular beam via supersonic expansion from a cryogenically cooled beam source only populate the lowest rotational states: j = 0 (%) for p -H 2, j = 0 (25%) and j = 1.
