Physics Letters B, 1999•ElsevierThe p ̄ D and p ̄ 4He total annihilation cross sections have been measured with the
Obelix apparatus at LEAR at, respectively, three and two values of the p ̄ incident
momentum between 70 MeV/c and 36 MeV/c. The values of the p ̄ D annihilation cross
section, at such low energies, are in agreement with a surprising result obtained in a recent
low statistics measurement of the antiprotonic deuterium Kα X-rays [M. Augsburger et al.,
Phys. Lett. B 461 (1999) 417](see following article), concerning the unexpected narrow width …
