The He–CaH„2S¿... interaction. II. Collisions at cold and ultracold temperatures
We present cross sections for rotational, vibrational, and fine-structure transitions in He–CaH(S) collisions at cold and ultracold temperatures calculated using the ab initio potential energy surface reported in the preceding paper. Rotational quenching is fast, vibrational quenching is slow. The spin-rotational interaction, although small and having no influence at temperatures above 10 K, ch...
متن کاملStudy of B → ψ(2S)K and B → ψ(2S)K ∗ (892) decays (CLEO Collaboration)
Color-suppressed decays of B mesons to final states with ψ(2S) mesons have been observed with the CLEO detector. The branching fractions for the decays B+ → ψ(2S)K+, B+ → ψ(2S)K∗(892)+, B0 → ψ(2S)K0, and B0 → ψ(2S)K∗(892)0 are measured to be (7.8±0.7±0.9)×10−4 , (9.2±1.9± 1.2)× 10−4, (5.0± 1.1± 0.6)× 10−4, and (7.6± 1.1± 1.0)× 10−4, respectively, where the first uncertainty is statistical and t...
متن کاملWorking with 2s and 3s
We establish an equivalent condition to the validity of the Collatz conjecture, using elementary methods. We derive some conclusions and show several examples of our results. We also offer a variety of exercises, problems and conjectures.
متن کاملN-[(2S)-2-Chloropropanoyl]glycine
The title compound, C(5)H(8)ClNO(3), was prepared by the nucleophilic substitution reaction of (2S)-2-chloro-propanoyl chloride with glycine. The acetate group forms a dihedral angle of 84.6 (1)° with the mean plane of the C-NH-C=O fragment. In the crystal, the molecules are linked by N-H⋯O and O-H⋯O hydrogen bonds, generating a three-dimensional network, which consolidates the crystal packing.
