We have measured the K+ K-/pi+-pi- ratio R from pBAR annihilations in gaseous D2 and H-2 at atmospheric pressure. The measurement was performed with the OBELIX spectrometer. From the measured value in gaseous D2 (0.27+/-0.02) we infer a P wave contribution to p-pBAR annihilation in D2 of (18+/-7)%.

Abstract
We have measured the K+ K-/pi+-pi- ratio R from pBAR annihilations in gaseous D2 and H-2 at atmospheric pressure. The measurement was performed with the OBELIX spectrometer. From the measured value in gaseous D2 (0.27+/-0.02) we infer a P wave contribution to p-pBAR annihilation in D2 of (18+/-7)%.
