Abstract:

In the ordered states of solid ortho-H₂ and para-D₂ the rotons (J = 3 excitations) are studied in full details. It is shown that the rotons are strongly perturbed by the librons (J = 1 excitations) through the anharmonic term splitting one roton into a pair of roton and libron. The relevant self-energy part is evaluated self-consistently with the results in satisfactory agreement with the Raman scattering data by Hardy, Silvera and McTague. The previous theory of libron by Coll and Harris is also reexamined by the present method.
