[en] The observation of Λ-hypernuclear levels in /sub Λ/¹²C by associated production through the (π⁺,K⁺) reaction is reported. Spectrometers used in the measurements are discussed. The /sub Λ/¹²C excitation energy spectra were recorded at laboratory scattering angles of 5.6⁰, 10.3⁰, and 15.2⁰. The spectra show two major peaks - one attributed to the ground state, and one about 11 MeV higher in excitation. The peak near 11 MeV excitation energy is believed to be almost entirely composed of a multiplet of three J/sup π/ = 2⁺ states. Relativistic DWBA calculations imply support for the expectation that higher spin states are preferentially populated in the (π⁺,K⁺) reaction, compared to the (K^-,π^-) reaction in which lower spin states are excited. 29 refs., 40 figs
