### Abstract

Inclusive cross sections for positive pion absorption leading to final states including two or more protons have been measured with a large solid angle detector for incident pion energies from 30 to 135 MeV for targets with [Formula Presented] The mass dependences for the inclusive [Formula Presented] and total absorption cross sections for multiproton final states were found to be proportional to [Formula Presented] with [Formula Presented] These cross sections also were observed to have an energy dependence at energies below 150 MeV reflective of the importance of the [Formula Presented] resonance, similar to that observed for [Formula Presented] The inclusive cross sections for [Formula Presented] were found to be less than 10 mb for all targets at all energies. Estimates were also obtained for cross sections for pion absorption leading to [Formula Presented] and [Formula Presented] final states. Quasideuteron absorption contributions increase slowly with A, and the energy dependence of those contributions mirrors that for [Formula Presented] The data obtained here for multiproton final states indicate that a significant fraction of absorption events, increasing with A, most likely arises from final states containing fewer than two protons.
