We study e+-Na, e+-K, and e+-Rb scattering using the close coupling approach in the static and coupled static expansion schemes. We calculate partial wave elastic scattering phase shifts and total elastic and Ps formation cross sections up to an incident positron energy of 100 eV. The effect of the

## Abstract A positive change ΞΞ»/Ξ» of the decay constant of ^99^Tc^m^ has been observed on the application of an external electric field in K~2~TcX~6~ (X = F, Cl, Br, I). For its investigation the Tcβcomplexes were embedded as small conglomerates or more or less as isolated single molecules in a po
