Phys. Rev. D 12, 2677–2683 (1975)Determination of the pion-nucleon coupling constantReceived 19 May 1975; published in the issue dated 1 November 1975 A method for determining the pion-nucleon coupling constant f2 by the application of an interior dispersion relation to the B(+)πN scattering amplitude is presented and its advantages over other dispersion relation techniques are discussed. The method is used to calculate f2 for two sets of phase shifts: CERN 71 of Almehed and Lovelace and a modified version of the Carter, Bugg, and Carter solution, to obtain f2=(81.5±1.5)×10-3 and f2=(79.5±1.0)×10-3, respectively. © 1975 The American Physical Society URL:
