Theoretical Study of the Stereodynamics of the Reaction C( ³ P)+CH(X ² Π) and Its Isotopic Variants

Abstract

Vector correlations between products and reagents of the reaction C+CH and the isotopic variant reactions are calculated by employing the quasi-classical trajectory method based on the adiabatically 1 2 𝐴 ′′ double-many-bodyexpansion potential-energy surface computed and numerically fitted by Boggio-Pasqua et al. The normalized polarization-dependent differential cross-sections and the distributions of 𝑃 (𝜃𝑟), 𝑃 (𝜑𝑟) and 𝑃 (𝜃𝑟, 𝜑𝑟) at the selected collision energy are discussed in detail. The values of the product rotational alignment parameter ⟨𝑃2(𝑗 ′ • 𝑘)⟩ are also calculated and plotted as functions of the collision energy in the range 0.005-0.5 eV. The computed results show that the rotational polarizations of the product present pronounced different characters as the mass substituted atom increasing.

Two-Fermion Scattering on Momentum-Representation in a Trap and Their Periodic Phenomena

“…One can see from Refs. [16,17] that if we choose 𝜔 perfectly, for instance 6 Li and 23 Na, the interaction potential 𝑉 (𝑟) we choose in the numerical calculation is identical to the experimental values. During the numerical calculation, we have to confine the dimension of the Hilbert space by choosing 𝑛 < 17.…”
