All four methods of estimating Penning ionization cross-sections were used, and the best agreement was found for Eqn (21) (proportionality to atomic polarizability). Thus, this equation was applied for the final calculations. In all cases, the best fit was obtained with parameter m from Eqn (...

Node and edge features need to be defined before message passing. Here we use a total of 15 types of atomic feature (Supplementary Table6) and five types of bond feature (Supplementary Table7) to characterize them and their local chemical environment. Except for atomic mass, explicit valence,...
Relative molecular mass is the mass of a specie with respect to that of carbon-12. A specie with a relative molecular mass of 1 has exactly 1/12 the mass of carbon-12. Answer and Explanation: Become a Study.com member to unlock this answer! Create your account View this answer ...
The electron-pair intracule (relative motion)h(u)and extracule (center-of-mass motion)d(R)densities represent probability densities for the interelectronic distance and the center-of-mass radius of any pairs of electrons, respectively. For 102 atoms from He (atomic numberZ=2)to Lr(Z=103),...
