A search, for possible hyperon resonance states which decay into Σ+-π± or Λπ- from K- -meson capture processes on complex nuclei, in view of the recent development of the hyperon resonances, was made. In order to establish the hyperon resonances, an extensive pion energy-spectrum was studied in addition to the mass-spectrum. A calculation, assuming that the pion scatters singly with a nucleon inside the nucleus, fits the pion and hyperon kinetic energy spectra and the excitation of the residual nucleus for the (Λ, π) events very well, ifY0* (1405 MeV, T=0) production is taken into account. This model calculation also predicts the right position at about 100 MeV for the pion peak from the (Λ, π-) channel. As a consequence of the pion spectrum study it seems to be clear that the K--meson capture processes most likely occur uniformly inside the nucleus instead of on the surface of the nucleus. It is found that about 30 to 40 per cent of (Σ, π) events come through the Y0* resonance state. On the other hand, the estimate of Y0* (1385 MeV,T=1) production could not be obtained due to poor statistics.
