    "abstract": "Role of the Landau-Migdal parameters with the pseudovector ($g_a$) and the\ntensor coupling ($g_t$) is examined for the giant Gamow-Teller (GT) states in\nthe relativistic random phase approximation (RPA). The excitation energy is\ndominated by both $g_a$ and $g_t$ in a similar way, while the GT strength is\nindependent of $g_a$ and $g_t$ in the RPA of the nucleon space, and is\nquenched, compared with that in non-relativistic one. The coupling of the\nparticle-hole states with nucleon-antinucleon states is expected to quench the\nGT strength further through $g_a$.",
