    Proton decay in a nucleus: nonrelativistic treatment of nuclear effects
    (Physical review D, 1983) Fernández Pérez, Luis Antonio; Fernández Álvarez-Estrada, Ramón; Sánchez Gómez, J. L.
    In this paper, proton decay in a large nucleus is studied in the framework of SU(5) grand unification theory (GUT). By using a method based upon the Green s-function technique of many-body physics, nuclear effects on spectator and pole terms are computed. The decay width in the nucleus is found to be practically the same as in free space. However, nuclear effects are of considerable importance concerning the positron spectrum. A densitycorrelation expansion is introduced which is useful for carrying out a systematic study of nuclear effects in proton decay in a large nucleus. The method presented here can be easily extended to other GUT's or supersymmetric GUT's.

    Proton decay in a nucleus: effects of the nuclear surface
    (Physical review D, 1986) Fernández Álvarez-Estrada, Ramón; Fernández Pérez, Luis Antonio
    In this paper, a previously published method to deal with proton decay in nuclear rnatter is generalized in order to account for eA'ects coming from the nuclear surface. The treatment is applied to nucleon decay in 16^O and 56^Fe.
