The lowest-order correction in the hyperfine splitting of muonic /sup 4/He due to excitation of the effective (..mu..-He)/sup +/ nucleus is precisely evaluated numerically. The result is ..delta nu../sub 1//sup e/ = -45.670(8) MHz, in agreement with previous approximate analytic calculations. The mass-polarization correction to the hyperfine splitting is found to be ..delta nu../sub 1//sup m/ = 0.0785(2) MHz. The total perturbation-theory value for the hyperfine splitting is ..delta nu.. = 4464.3(1.8) MHz, which is consistent with experiments at the Swiss Institute for Nuclear Research and at the Clinton P. Anderson Meson Physics Facility at Los Alamos.
