Jun 24, 1993 · Detection of π+π- atoms with the DIRAC spectrometer at CERN. B. Adeva L. Afanasyev. +87 authors. P. Zrelov. Physics. 2004. The goal of the DIRAC experiment at CERN is to measure with high precision the lifetime of the π + π - atom (A 2π ), which is of order 3 x 10 -15 s, and thus to determine the s-wave ππ-scattering….
