Splet08. dec. 2011 · Scattered atoms exhibited a node in the k x = 0 plane—a dramatic manifestation of beyond s-wave scattering. The inner halo (I) is due to a process in which one atom in a colliding pair undergoes an inelastic transition to the n = 0 band, while the … Splet13. feb. 2009 · From an analysis of the contributions of s-wave and p-wave scatterings to the elastic cross section we estimate temperatures below which only s-wave scattering is dominant.

Splet14. sep. 2014 · The system is treated as four-centre problem in the centre-of-mass frame. The present ab-initio model is useful to study the two-atomic collisions at low energies, as well as cold energies. The new code is applied to study the scattering of positronium (Ps) … Spletintraspecies (a11 and a22) and interspecies (a12) s-wave scattering. Due to the particular properties of the singlet and triplet inter-atomic potentials [5] the s-wave scattering lengths of 87Rb atoms in the ground hyperfine states with F= 1 and F= 2 are very close to each other (the maxi-mum difference is around 5%). These two states in 87Rb,
Splet22. jan. 2014 · S wave is the zero angular momentum quantum number , l=0, and will correspond to a classical head on collision. P is l=1 and d l=2 which means higher angular momentum between scatterer and incoming. The atomic orbitals would give some … Splet22. maj 2006 · Photoassociation is the process in which two colliding atoms absorb a photon to form an excited molecule. The development of laser-cooling techniques for producing gases at ultracold (<1 mK) temperatures allows photoassociation spectroscopy to be performed with very high spectral resolution.

Here, Ueg is proportional to the s-wave scattering length (aeg) and independent of temperature (T), while V scales as k2 Tb 3, with b the p-wave scattering volume and kT the wave number associated with the ther-maldeBrogliewavelength(kT ¼
SpletA salient feature of cold atom systems is that field-induced Feshbach resonance can tune the scattering length between atoms (Inouye et al., 2001), which determines the atom–atom interaction. A Feshbach resonance occurs when a quasibound molecular state in a closed channel has energy equal to that of two colliding atoms in an open channel.
