Binding energies and nonradiative decay rates of $H\! ed\mu $-molecular   ions
  The method of hyperspherical "surface" functions has been applied to the calculation of eigenvalues and eigenfunctions of muonic molecular ions $^{3,4}\! H\! ed\mu $. Binding energies and nonradiative decay rates for the states of the total angular momentum $L=0,~1,~2$ have been obtained.
