The observation of ..lambda..-hypernuclear levels in 1 /sub ..lambda..//sup 2/C by associated production through the (..pi../sup +/,K/sup +/) reaction is reported. The /sub ..lambda..//sup 12/C excitation-energy spectra were recorded at laboratory scattering angles of 5.6/sup 0/, 10.3/sup 0/, and 15.2/sup 0/. They show two major peaks: one attributed to the ground state, and one about 11 MeV higher. These results are compared to the strangeness-exchanging (K/sup -/,..pi../sup -/) reaction. The measured cross sections are compared to relativistic distorted-wave Born-approximation calculations.
