Ultracold collisions of metastable helium atoms
نویسندگان
چکیده
We report scattering lengths for the Σg , Σu and Σg adiabatic molecular potentials relevant to collisions of two metastable 2 3S helium atoms as a function of the uncertainty in these potentials. These scattering lengths are used to calculate experimentally observable scattering lengths, elastic cross sections and inelastic rates for any combination of states of the colliding atoms, at temperatures where the Wigner threshold approximation is valid.

Frequency shifts of photoassociative spectra of ultracold metastable Helium atoms : a new measurement of the s-wave scattering length
– We observe light-induced frequency shifts in one-color photoassociative spectra of magnetically trapped He atoms in the metastable 2S1 state. A pair of ultracold spinpolarized 2S1 helium atoms is excited into a molecular bound state in the purely long range 0+u potential connected to the 2 S1−2 P0 asymptote. The shift arises from the optical coupling of the molecular excited bound state with ...
متن کاملGiant helium dimers produced by photoassociation of ultracold metastable atoms.
We produce giant, purely long-range helium dimers by photoassociation of metastable helium atoms in a magnetically trapped, ultracold cloud. The photoassociation laser is detuned close to the atomic 2(3)S1-2(3)P0 line and produces strong heating of the sample when resonant with molecular bound states. The temperature of the cloud serves as an indicator of the molecular spectrum. We report good ...
متن کاملHeteronuclear ionizing collisions between laser-cooled metastable helium atoms
We have investigated cold ionizing heteronuclear collisions in dilute mixtures of metastable (2 S1) He and He atoms, extending our previous work on the analogous homonuclear collisions [R. J. W. Stas et al., PRA 73, 032713 (2006)]. A simple theoretical model of such collisions enables us to calculate the heteronuclear ionization rate coefficient, for our quasi-unpolarized gas, in the absence of...
متن کاملFeasibility of measuring surface electron spin dynamics by inelastic scattering of metastable helium atoms
The application of inelastic scattering of monoenergetic beams of metastable 2S helium atoms (He*) from surfaces of magnetic insulators to study the dynamical properties of surface electron-spin systems is considered. The study is based on a calculation of the differential inelastic reflection coefficient for magnetic scattering using a distorted-wave Born approximation approach. The NiO~001! s...
متن کاملRAPID COMMUNICATION Upper Limit for Quenching Rate Coefficient for cold electron–Metastable-Atom Collisions
A simple model based on 100% quenching of metastables by threshold electrons transmitted to short distances on the polarization potential is employed. Values of the quenching rate coefficients of 1.6 × 10−6 cm/s at threshold and 0.92× 10−6 cm/s at 50 K are estimated for electron collisions with metastable Xenon and 1.33× 10−6 cm/s at threshold for metastable Calcium.
