Conservation of Angular Momentum - Alignment - Internal Degree of Freedom — •Victor Wei-Keh WU1 and 2 — 1Victor Basic Research Laboratory e. V., Kurt-Schumacher-Str. 12, D-33615 Bielefeld, Germany (http://www.uni-bielefeld.de/ fkure) — 2
Conservations of energy and angular momemtum (rotations of interacting particles and
system) are two rules as well as conditions to treat and solve the problems of reacting
particles. The values of alignment within the whole investigated Erel,
e.g., 0.01≤Erel≤3.0 eV of the ideal type of chemical reaction
H1 + H2 → H1H2 + L, e.g., Ba + HBr →
BaBr + H can be well predicted by CPOAM (Constrained Product Orbital Angular
Momentum) model. The more comparable of mass of L with H2 or H1 is, the
more is the deviation of the calculated value P2 of alignment from the
asymptotic value -0.5. Whether the amount of such deviation can be correlated
with the internal degrees of freedom of the multi atomic particle L, which
should not be neglected, e.g., in the QCT calculation, is to be kept
investigated, for what the multi particle QCT program should be applied.
