[en] Bound and quasi-bound states of mesic molecular ions have been calculated in the framework of the Born-Oppenheimer approximation. The energy levels, potential humps, and lifetimes with respect to predissociation of Heμ⁺ and Neμ⁺ quasi-bound states are determined. Diabatic and non adiabatic corrections are estimated and discussed

[en] The time correlation functions of experimental interest are calculated for a powder sample of a rotatory crystal where the allowed orientations of the molecules have the general multiplicity 24 of the cubic group 0. (orig.)

[en] @tomic 2012 tested international participants on their response to a nuclear/radiological incident with a cyber dimension. While successful as an early step towards establishing a global knowledge community, @tomic 2012 demonstrated a need for regular iterative exercises that build upon previous learning so that future incident responders have a roadmap for effective action. Only by expanding a crisis-led understanding of radiological issues, good forensics practice, cybersecurity and media and crisis communications, can the highly plausible elements of a scenario like @tomic 2012’s be potentially mitigated.

[en] Results of incoherent quasielastic neutron scattering experiments on quinuclidine, C₇H₁₃N, in its plastic phase (room temperature) are presented. The observed quasielastic spectra are compared to several models for the rotational motion of the molecules. It is found that the data support a picture, where the molecules perform 90⁰-reorientations about crystallographic C₄-axes with a residence time of (24.8+-2.5).10^-12s, and 120⁰-reorientations about the molecular C₃-axis with a residence time of (9.6+-2.0).10^-12s
