Quasielastic Deuteron and Triton Knockout from Lithium Isotopes by Intermediate-Energy Pions.

Quasielastic deuteron and triton knockout from ⁶Li and ⁷Li nuclei that was induced by a π^–-meson beam of momentum p₀ = 0.72 and 0.88 GeV/c was studied under conditions of full kinematics. The experiment was performed at the Institute of Theoretical and Experimental Physics (ITEP, Moscow) by using a 3-m magnetic spectrometer equipped with spark chambers. The distributions with respect to the momenta of quasideuteron and quasitriton internal motion, the excitation-energy spectra of residual nuclei, and the effective numbers of quasideuterons in ⁶Li and ⁷Li nuclei were obtained.© 2005 Pleiades Publishing, Inc.
