Recent experimental progress at the cyclotron of the RCNP Osaka, Japan, allows measurements ofintermediate-energy inelastic polarized proton scattering at and near 0° combined with high energyresolution. We plan to utilize this new experimental opportunity for an investigation of the nature ofelectromagnetic dipole modes in heavy nuclei at low energies currently at the heart of nuclearstructure research. Based on the results achieved in a benchmark experiment on 208Pb we plansystematic studies at different shell closures and of the role of deformation. The envisagedexperimental program ideally complements the research goals of the nuclear structure andastrophysics part of the Collaborative Research Centre 634 at the S-DALINAC accelerator at the TUDarmstadt using different experimental probes.

最近在日本大坂RCNP回旋加速器上的实验进展，允许测量0 °和接近0°的中能非弹性极化质子散射，并结合高能量分辨率。我们计划利用这一新的实验机会，对目前处于核结构研究核心的低能重核中电磁偶极模的性质进行研究。基于208 Pb基准实验的结果，我们计划在不同的壳层闭合和变形的作用下进行系统的研究。设想的实验计划理想地补充了合作研究中心634的核结构和天体物理学部分的研究目标，该中心位于图达姆施塔特的S-DALINAC加速器，使用不同的实验探针。
