Relaxation times of k=0 rotons are calculated in the low concentration of orthohydrogen in solid paprahydrogens by considering the electric quadrupole-quadrupole interaction between molecules and neglecting phonon contributions. The calculated results are in good agreements with the recent Rgman scattering experiment, although there is no adjustable parameter.
