Observation of nondispersing classical-like molecular rotation
Using the technique of an optical centrifuge, we produce rotational wave
packets which evolve in time along either classical-like or non-classical
trajectories. After releasing O2 and D2 molecules from the centrifuge, we track
their field-free rotation by monitoring the molecular angular distribution with
velocity map imaging. Due to the dispersion of the created rotational wave
packets in oxygen, we observe a gradual transition between "dumbbell"-shaped
and "cross"-shaped distributions, both rotating with a classical rotation
frequency. In deuterium, a much narrower rotational wave packet is produced and
shown to evolve in a truly classical non-dispersing fashion
Embedding generic employability skills in an accounting degree: development and impediments
This paper explores and analyses the views of, and effects on, students of a project that integrated the development of employability skills within the small group classes of two compulsory courses in the first year of an accounting degree at a UK university. The project aimed to build, deliver and evaluate course materials designed to encourage the development of a broad range of employability skills: skills needed for life-long learning and a successful business career. By analysing students' opinions gathered from a series of focus groups spread throughout the year, three prominent skill areas of interest were identified: time management, modelling, and learning to learn. Further analysis highlighted the complex nature of skills development, and brought to light a range of impediments and barriers to both students' development of employability skills and their subject learning. The analysis suggests the need for accounting educators to see skills development as being an essential element of the path to providing a successful accounting education experience
Measurement of the Difference in R=σ_L/σ_T and of σ^A/σ^D in Deep-Inelastic e-D, e-Fe, and e-Au Scattering
We measured the differences in R=σ_L/σ_T and the cross-section ratio σA/σD in deep-inelastic electron scattering from D, Fe, and Au nuclei in the kinematic range 0.2≤x≤0.5 and 1≤Q^2≤5 (Gev/c)^2. Our results for R^A-R^D are consistent with zero for all x and Q^2, indicating that possible contributions to R from nuclear higher-twist effects and spin-0 constituents in nuclei are not different from those in nucleons. The European Muon Collaboration effect is reconfirmed, and the low-x data from all recent experiments, at all Q^2, are now in agreement
