The semiclassical distorted wave model is developed to describe (π -, K+) inclusive spectra related to ∑- formation measured at KEK with pπ = 1.2 GeV/c. The shape and magnitude of the spectrum obtained with a 28Si target are satisfactorily reproduced using a repulsive ∑-nucleus potential whose strength is of the order of 30-50 MeV. This strength is not as large as the value of more than 100 MeV obtained using the estimation presented in the report of the experiment.
