Electromagnetic Annihilation of Antiprotons

Phys. Rev. 103, 751 – Published 1 August 1956
Laurie M. Brown and Murray Peshkin


The familiar model of a nucleon as a Dirac particle with Pauli anomalous magnetic moment is used to obtain cross sections for antiproton annihilation into two photons, two electrons, or two muons. The two-photon lifetime of the n S01 state of the proton-antiproton atom is 2×10-15n3 sec.
