Effects of impurity atoms and molecules on the lifetime of antiprotonic helium atoms

Delayed annihilation time spectra of antiprotons (DATS) in room temperature helium gas have been studied as a function of the concentration of admixed noble gases (Ne, Ar, Kr, Xe) as well as molecular gases (N_2,O_2,H_2) at the low energy antiproton ring (LEAR) at CERN. The DATS were a superposition...
