It is shown by direct numerical calculations that the introduction of two dynamical variables, which is necessary for the description of real hypernuclei, does not lead to significant mathematical difficulties. It is found that the inclusion of density oscillations of the nucleons of the hypernucleus increases the ..lambda.. particle separation energy B/sub ..lambda../ in some cases by a factor 1.5. The problem is studied of determination of the ..lambda..N potential using the ..lambda..p scattering length and effective range as well as the value of B/sub ..lambda../ of the /sup 5//sub ..lambda../He hypernucleus. By means of one of the ..lambda..N potentials established, low-energy ..lambda../sup 4/He scattering is calculated.
