Cold and ultracold NH-NH collisions in magnetic fields
Elastic and spin-changing inelastic collision cross sections are presented for cold and ultracold magnetically trapped NH. The cross sections are obtained from coupled-channel scattering calculations as a function of energy and magnetic field. We specifically investigate the influence of the intramolecular spin-spin, spin-rotation, and intermolecular magnetic dipole coupling on the collision dy...
متن کاملCold and ultracold NH-NH collisions: the field-free case.
We present elastic and inelastic spin-changing cross sections for cold and ultracold NH(X (3)Σ(-)) + NH(X (3)Σ(-)) collisions, obtained from full quantum scattering calculations on an accurate ab initio quintet potential-energy surface. Although we consider only collisions in zero field, we focus on the cross sections relevant for magnetic trapping experiments. It is shown that evaporative cool...
متن کاملCold N+NH collisions in a magnetic trap.
We present an experimental and theoretical study of atom-molecule collisions in a mixture of cold, trapped N atoms and NH molecules at a temperature of ∼600 mK. We measure a small N+NH trap loss rate coefficient of k(loss)(N+NH)=9(5)(3)×10(-13) cm(3) s(-1). Accurate quantum scattering calculations based on ab initio interaction potentials are in agreement with experiment and indicate the magn...
متن کاملUltracold molecular collisions in combined electric and magnetic fields
We consider collisions of electric and magnetic polar molecules, taking the OH radical as an example, subject to combined electric and magnetic static fields. We show that the relative orientation of the fields has an important effect on the collision processes for different fields’ magnitudes at different collision energies. This is due to the way the molecules polarize in the combined electri...
متن کاملfor “ Quantum reactive scattering of ultracold NH ( X 3 Σ − ) radicals in a magnetic trap ”
QUANTUM REACTIVE SCATTERING METHOD In this section, we outline the quantum scattering algorithm used to calculate the total NH + NH reactive cross sections. Before discussing our approach in detail, let us recall the basics of already established single-arrangement reactive scattering methods. Conventional single-arrangement algorithms combine a standard inelastic scattering calculation, e.g., ...
