Calculation of radial matrix elements and radiative lifetimes for highly excited states of alkali atoms using the Coulomb approximation
نویسنده
چکیده
2014 Radial matrix elements have been computed involving highly excited states of alkali atoms. An entirely analytical Coulomb method has been used. Particular attention has been paid in the choice of the cut criterion. The extensive data are available from the author upon request and can be used to compute, for example, oscillator strengths, radiative lifetimes, branching ratios and polarizabilities of alkali Rydberg states. In order to test the results, radiative lifetimes have been derived for highly excited (10 ~ n ~ 28), S, P, D and F states of alkali atoms. The computed lifetimes are reported and are observed to be in good agreement with the available experimental data. LE JOURNAL DE PHYSIQUE TOME 40, MAI 1979, Classification Physics Abstracts 32.70

Single-valence electron atoms are an important class of atoms. Their oscillator strengths are their important properties. Knowing the oscillator strengths one can easity calculate the transition probabilities of the spectral lines and hence the lifetimes of energy levels of most atoms. The oscillator strengths of the spectral lines of most atoms are not knoen with sufficient accuracy due to t...

Wepresent an object-oriented Python library for the computation of properties of highly-excited Rydberg states of alkali atoms. These include single-body effects such as dipole matrix elements, excited-state lifetimes (radiative and black-body limited) and Stark maps of atoms in external electric fields, as well as two-atom interaction potentials accounting for dipole and quadrupole coupling ef...

متن کاملRadiative lifetimes of highly excited states in rubidium
2014 Measurements have been made of the natural radiative lifetimes of highly excited rubidium (9 ~ n ~ 18) S and D states. These results, as well as those already published concerning P and F states, agree well with the theoretical lifetimes calculated by the Bates-Damgaard method. J.

متن کاملMagic wavelengths for the np-ns transitions in alkali-metal atoms
Extensive calculations of the electric-dipole matrix elements in alkali-metal atoms are conducted using the relativistic all-order method. This approach is a linearized version of the coupled-cluster method, which sums infinite sets of many-body perturbation theory terms. All allowed transitions between the lowest ns, np1/2, np3/2 states and a large number of excited states are considered in th...
