G. P. Homem, R. T. Sugohara, I. P. Sanches, M. T. Lee, and I. Iga<br/>In this work, we report an experimental cross-section determination of elastic electron collisions with tetrahydrofuran in the intermediate-energy range. More specifically, absolute differential cross sections are measured and reported in the (50–1000) eV range. The measurements were performed usi...<br/>[Phys. Rev.

Mathey, Eite Tiesinga, Paul S. Julienne, and Charles W. Clark<br/>We propose a cooling mechanism for ultracold fermionic atom ensembles, which capitalizes on the energy dependence of inelastic collisions near a Feshbach resonance. We first discuss a single magnetic resonance and find that the final temperature and cooling rate is limited by the resonance width.
