A method is proposed for taking into account the influence of the quadrupole interactions on the dipole relaxation of the μ + -meson spin in a metal. The method can be used in those cases when the quadrupole interaction of the μ f meson and the nuclei of the metal is much larger than their dipole interaction. The volume expansion of the tantalum and indium lattices by impurity μ+ mesons is determined.
