Abstract

New ^6,7Li(π⁺, ³He) ^3,4 He differential cross sections are combined with earlier data to study the reaction's energy dependence between threshold and T_π = 60 MeV. The cross sections for the ⁷Li(π⁺, ³He'³He)n and ⁷Li(π⁺, ³He³He)p reactions, in which the nucleon is nearly at rest, are also measured and found to have magnitudes similar to the ⁶Li(π⁺,³He)³He cross section. The ³He³H + p channel has a factor of 4(±2) higher yield than the ³He³He + n channel. The results are examined in terms of two different models for the reaction mechanism.
