Quasielastic deuteron and triton knockout from lithium isotopes by intermediate-energy pions

Abstract

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.
