The combined cross section for absorption and charge exchange interactions of
positively charged pions with carbon nuclei for the momentum range 200 MeV/c to
300 MeV/c have been measured with the DUET experiment at TRIUMF. The
uncertainty is reduced by nearly half compared to previous experiments. This
result will be a valuable input to existing models to constrain pion
interactions with nuclei.Comment: 29 figures, 7 tables. To be submitted to PR
