Rho-nucleon tensor coupling and charge-exchange resonances

The Gamow–Teller resonance in ²⁰⁸Pb is discussed in the context of a self-consistent RPA, based on the relativistic mean field theory. We inquire on the possibility of substituting the phenomenological Landau–Migdal force by a microscopic nucleon–nucleon interaction, generated from the rho-nucleon t...

description The Gamow–Teller resonance in ²⁰⁸Pb is discussed in the context of a self-consistent RPA, based on the relativistic mean field theory. We inquire on the possibility of substituting the phenomenological Landau–Migdal force by a microscopic nucleon–nucleon interaction, generated from the rho-nucleon tensor coupling. The effect of this coupling turns out to be very small when the short range correlations are not taken into account, but too large when these correlations are simulated by the simple extraction of the contact terms from the resulting nucleon–nucleon interaction.
