Measurement of the breakup probability of pi+ pi- atoms in a nickel target with the DIRAC spectrometer
The DIRAC Collaboration aims to determine the lifetime of the pionium atom, a pi+pi- bound state, by measuring the breakup probability of such a bound state. This breakup probability measurement with the DIRAC spectrometer at CERN searches for an excess of pi+pi- pairs from breakup at very low relat...
