Muon capture, continuum random phase approximation, and in-medium renormalization of the axial-vector coupling constant.
We use the continuum random phase approximation to describe the muon capture on C, O and Ca. We reproduce the experimental total capture rates on these nuclei to better than 10% using the free nucleon weak form factors and two di erent residual interactions. However, the calculated rates for the same residual interactions are signi cantly lower than the data if the in-medium quenching of the ax...
متن کامل6 Dirac Sea Contribution in Relativistic Random Phase Approximation
In the hadrodynamics (QHD) there are two methods to take account of the contribution of negative-energy states in the relativistic random phase approximation (RRPA). Dawson and Furnstahl made the ansatz that the Dirac sea were empty, while according to the Dirac hole theory the sea should be fully occupied. The two methods seem contradictory. Their close relationship and compatibility are explo...
متن کاملIsoscalar compression modes in relativistic random phase approximation
A fully consistent relativistic RPA calculation is performed for the monopole and dipole compression modes in nuclei. The emphasis is put on the effects of Dirac sea states which are generally neglected in relativistic RPA calculations. It is found that these effects can be quite important for the isoscalar monopole mode. The main contributions from the pairs of Fermi to Dirac sea states are th...
متن کاملIsoscalar dipole mode in relativistic random phase approximation
The isoscalar giant dipole resonance structure in Pb is calculated in the framework of a fully consistent relativistic random phase approximation, based on effective mean-field Lagrangians with nonlinear meson self-interaction terms. The results are compared with recent experimental data and with calculations performed in the HartreeFock plus RPA framework. Two basic isoscalar dipole modes are ...

In the relativistic random phase approximation there are two methods to take account of the contribution of negative energy states. Dawson and Furnstahl made the ansatz that the Dirac sea were empty, while the Dirac hole theory postulated the sea should be fully occupied. The two methods seem contradictory. Their close relationship and compatibility are studied and enunciated. PACS: 21.60. Jz, ...
