“…Most notably, with the use of the Oslo method, the experimentally obtained γSFs seem to be in agreement with gBA [6]. On the other hand, the results from the 208 Pb(p, p ) experiment at RCNP in Osaka are inconclusive [7,8].…”

“…[30,31]. In more recent experiments on the dipole response, a concentration of strength has been observed in the low-energy region [32,33], being most prominent in neutron-rich nuclei. Its origin was attributed to the coherent oscillation of the neutron skin around the isospin-saturated core, which is called pygmy dipole resonance (PDR).…”

A thermal extension of the relativistic nuclear field theory is formulated for the nuclear response. The Bethe-Salpeter equation (BSE) with the time-dependent kernel for the particle-hole response is treated within the Matsubara Green's function formalism. We show that, with the help of a temperature-dependent projection operator on the subspace of the imaginary time (time blocking), it is possible to reduce the BSE for the nuclear response function to a single frequency variable equation also at finite temperature. The approach is implemented self-consistently in the framework of quantum hadrodynamics based on the meson-nucleon Lagrangian. The method is applied to the monopole, dipole and quadrupole response of 48 Ca and to the dipole response of the tin isotopes 100,120,132 Sn, in particular, to a study of the evolution of nuclear collective oscillations with temperature. The article is dedicated to the memory of Pier Francesco Bortignon and devoted to the developments related to his pioneering ideas.

Experimental M1 response of Ar40 as a benchmark for neutrino-nucleus scattering calculations

The excitation of atomic nuclei via magnetic dipole transitions is closely related to the inelastic neutral-current neutrino-nucleus (NC-νA) scattering process due to the similarity of the transition operators. NC-νA-scattering serves for the detection of supernova neutrinos and poses a significant source of background in modern liquid-argon based high-energy neutrino detection experiments. In order to enable tests of the reliability of predictions for neutrino-nucleus scattering, the magnetic dipole response of 40 Ar below 7.7 MeV was characterized in a nuclear resonance fluorescence experiment using quasi-monoenergetic gamma-ray beams. The linear polarization of the beams allowed for assignments of electric or magnetic character to previously known dipole excitations. A total magnetic dipole strength of 0.36 +0.04 −0.05 µ 2 N was identified in the energy range of the present experiment. Combined with data from previous measurements, the full magnetic dipole strength of 40 Ar below the neutron separation threshold was investigated. Due to the low background in the energy range within the bandwidth of the gamma-ray beams, the previous sensitivity limit was improved. A large-scale nuclear shell model calculation in the sd-f p space satisfactorily agrees with the data in terms of excitation energies and strengths of the observed 1 + states. CONTENTS
