Publisher

Abstract

Scattering lengths in the systems 4 He, 6 Li, 7 Li, 12 C, 16 O, 17 O, and 18 O are derived from the measurements of the strong interaction atomic level shifts in the corresponding antiprotonic atoms. The Coulomb corrections to the scattering lengths are evaluated and it is found that they are large.

Low-energy antiproton scattering by atoms and Coulomb level shifts

Olgierd Dumbrajs

A relationship between the low-energy antiproton-atom scattering parameters and Coulomb level shifts is derived. The corresponding scattering lengths are calculated for the p\ifmmode\bar\else\textasciimacron\fi{}-${\mathrm{He}}^{+}$ system on the basis of energy level shifts evaluated earlier by means of the Born-Oppenheimer approximation.

Scattering-length determination from trapped pairs of atoms

Sanjiv Shresta, Eite Tiesinga, Carl J. Williams

A method is described for estimating effective scattering lengths via spectroscopy on a trapped pair of atoms. The method relies on the phenomena that the energy levels of two atoms in a harmonic trap are shifted by their collisional interaction. The amount of shift depends on the strength of the interaction (i.e., scattering length). By combining the spectra of the trap state energy levels and a suitable model for the effective scattering length, an estimate for the latter may be inferred. Two practical methods for measuring the trap spectra are proposed and illustrated in examples. The accuracy of the scheme is analyzed and requirements on measurement precision are given.

Modification of the method of polarized orbitals for electron-alkali-metal scattering: Application to e -Li

A. K. Bhatia, Aaron Temkin, A. Silver +1 more

The method of polarized orbitals is modified to treat low-energy scattering of electrons from highly polarizable systems, specifically alkali-metal atoms. The modification is carried out in the particular context of the $e$-Li system, but the procedure is general; it consists of modifying the polarized orbital, so that when used in the otherwise orthodox form of the method, it gives (i) the correct electron affinity of the negative ion (in this case ${\mathrm{Li}}^{\ensuremath{-}}$), (ii) the proper (i.e., Levinson-Swan) number of nodes of the associated zero-energy scattering orbital, and (iii) the correct polarizability. A procedure is devised whereby the scattering length can be calculated from the (known) electron affinity without solving the bound-state equation. Using this procedure we adduce a $^{1}S$ scattering length of $8.69{a}_{0}$. (The $^{3}S$ scattering length is $\ensuremath{-}9.22{a}_{0}$.) The above modifications can also be carried out in the (lesser) exchange adiabatic approximation. However, they lead to qualitatively incorrect $^{3}S$ phase shifts. The modified polarized-orbital phase shifts are qualitatively similar to close-coupling and elaborate variational calculations. Quantitative differences from the latter calculations, however, remain; they are manifested most noticeably in the very-low-energy total and differential spin-flip cross sections.

Scattering lengths for collisions of ground state and metastable state hydrogen atoms

Michael J. Jamieson, A. Dalgarno, John M. Doyle

Scattering lengths for the collisions of ground and metastable state hydrogen atoms interacting via the B′1∑u +, EF 1∑g +, e3∑u + and h3∑g + molecular potentials are evaluated from published ab initio Born-Oppenheimer potentials with adiabatic corrections, matched to multipole expansions at large interatomic separations. It is demonstrated that the scattering lengths are very sensitive to the connections between the ab initio potentials and their asymptotic forms and the need is shown for accurate interatomic potential calculations at greater separations than are currently available. The density-dependent shift and broadening of the 1S–2S transition frequency in atomic hydrogen caused by two-body elastic collisions are presented.

Variable Phase Method Used to Calculate Ultracold Scattering Properties of 7 Li 33 Cs

Du Bing-Ge, Sun Jin-Feng, Zhang Ji-Cai +3 more

Elastic scattering properties of singlet and triplet states of 7 Li 133 Cs at ultralow temperatures are calculated using the constructed potential curves gleaned from high-precision spectroscopy measurement. We show how to reach the scattering length and the number of bound states via the variable phase method. The scattering lengths of the singlet and triplet states of 7 Li 133 Cs are 50.5a.u. and — 135.7a.u., respectively. We derive two corrections, arising from long range interactions, accurately to at least first order, which provide upper and lower computed bounds to the scattering length. Our results are consistent with the recent experimental data and the theoretical calculation.

Higher Order Hadronic Energy Level Shifts in Protonium

Xinwei Kong, F. Ravndal

Using effective field theory for a proton and antiproton bound in a Coulomb potential, the shift of the ground state energy level is calculated to arbitrary order in the scattering length. Including the next order contact interaction, the correction due to the effective range parameter can also be obtained.
