Results of a kinematically complete experiment on backward pi (-)d quasielastic scattering by Li-6 are presented. The experiment was carried out at the ITEP 3-m magnetic spectrometer with pion beams of momenta 0.72, 0.88, and 1.28 GeV/c. The Fermi-motion parameters of a quasideuteron cluster and the effective number of quasideuterons in Li-6 are determined for the Li-6(pi (-), pi (-)d)He-4 reaction. These values agree well with the proton- and electron-beam measurements. The possibility of observation of the effects of deuteron wave-function modification in nuclear matter is discussed for this reaction. (C) 2001 MAIK "Nauka / Interperiodica".
