Energy spectra of(Formula presented.)C and(Formula presented.)Fe have been measured by means of (π+, K+) reactions at the KEK 12 GeV PS. The spectrometer PIK, which has large angular and momentum acceptance and medium energy resolution, has been constructed to study the reaction. The differential cross-section of the (π+, K+) reaction at forward angles θK∼(0÷6)o for the ground state of(Formula presented.)C and that for the effectively Λ-bound region of(Formula presented.)Fe agree well with the DWIA calculation using single-particle Λ wave functions obtained from a Woods-Saxon potential. The spectrum of(Formula presented.)Fe is consistent with the DWIA calculation using the realistic distribution of the hole-state strengths in55Fe.
