The distorted wave–peripheral three-body coupling model has been applied for knockout of particles bound in l = 1 state. As an example the ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$(α,2α${)}^3$H reaction at 77, 99, and 119 MeV has been analyzed. The distorted wave impulse approximation peripheral three-body coupling model calculations are compared with the conventional kinematic coupling approximation and with the data. © 1996 The American Physical Society.
