Bound-free pair production cross section in heavy-ion colliders from the equivalent photon approach

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/199514Exact calculations of the electron-positron pair production by a single photon in the Coulomb field of a nucleus with simultaneous capture of the electron into the K-shell are discussed for different nuclear charges. Using the equivalent photon method of Weizsaecker and Williams, a simple expression for the bound-free production of electron-positron pairs by colliding very-high-energy fully stripped heavy ions is derived for nuclei of arbitrary charge.4 pages, 2 figures, style file includedNuclear TheoryBound-free pair production cross section in heavy-ion colliders from the equivalent photon approachtext
