    Inverse Beta-Decay of Polarized Neutron in Curved Spacetime in the Presence of Strong Magnetic Field
    (Addis Ababa University, 2014-06) Tibesso, Tahir; Wetro, Legesse (PhD)
    We calculate the cross section of the inverse beta decay process, e+n ! p+e􀀀 in curved spacetime in the presence of strong magnetic eld and.Using exact solutions of the Dirac equation in a curved space-time and Spinors of the Dirac Equation and its solution In Robertson-Walker Spacetime, we nd the cross section for arbitrary polarization of the initial neutrons.The magnetic eld might provide a net polarization of the neutrons, which we take into account
