The electric dipole strength distribution in ^{40}Ca between 5 and 25 MeV has been determined at RCNP, Osaka, from proton inelastic scattering experiments at very forward angles. Combined with total photoabsorption data at higher excitation energy, t

Publikováno v: Physical Review C. 103
Background: Numerous studies of the ground-state decay of the pygmy dipole resonance (PDR) have been carried out in the past. However, data on the decay of the PDR to low-lying excited states is still very scarce due to limitations of the sensitivity

On the excitation of the $$2^+_1$$ state in $$^{12}$$C in the $$(e,e'\gamma )$$ reaction
Autor: V. Yu. Ponomarev, D. H. Jakubassa-Amundsen
Publikováno v: The European Physical Journal A. 56
The excitation of the carbon $2^+$ state at 4.439 MeV by $70-150$ MeV electron impact and its subsequent decay to the ground state by photon emission is described within the distorted-wave Born approximation. The transition densities are obtained fro

Multipole Response of Ni and Sn Isotopes and its Momentum Dependence
Autor: E. Mavrommatis, V. Yu. Ponomarev, Panagiota Papakonstantinou, Jochen Wambach
Publikováno v: HNPS Advances in Nuclear Physics. 12:110
We have used a self-consistent Skyrme-HF plus Continuum RPA model to study the low-multipole response of stable and neutron/proton-rich Ni and Sn isotopes using suitable Skyrme parametrizations. Experimental studies of these nuclei are being planned
