Semi-empirical potential energy surfaces for alkali-trimers are derived from the simplest form of London's approximation, by evaluating the Coulomb and exchange integrals as half of the sum and difference of two new interaction potential curves for the 1Σg+ and 3Σu+ states of the corresponding alkali dimers. The trimers attain maximum stability in their linear symmetric configuration. The force constants corresponding to stretching and bending deformations of the homonuclear trimers have been calculated for the linear symmetric configuration. Unlike the stretching, the bending deformation is seen to be very much insensitive to the ground state energy variation of the trimers.

Quasi Bound State

Necessary conditions of quasi-bound state formation of η-meson with isotopes3He,4He have been found within the framework of optical potential model. These conditions have been compared with the findings about helium nucleus densities and with the available information about ηN-scattering length. Thus, we have concluded that within the framework of discussed model η−3He quasi-bound state formation is not possible, but η−4He quasi-bound state formation is possible with great probability.
