Using electrons to observe the structure of unstable nuclei

05.09.2011
Unique experimental approaches and persistence have paid off for researchers determined to resolve the structure of unstable nuclei at the RIKEN Nishina Center for Accelerator-Based Science

Observing the structure of collapsing unstable atomic nuclei using electrons is an experimental goal that has not been achieved anywhere in the world. Masanori Wakasugi, director of the Instrumentation Development Group at the RIKEN Nishina Center for Accelerator-Based Science (RNC), is working on this challenging issue.

The current theoretical model of the atomic nucleus has been constructed with major contributions from electron-scattering experiments, in which electrons are collided with stable atomic nuclei to visualize the nuclear structure.

In recent years, however, a wide range of experiments on the properties of unstable atomic nuclei has revealed a number of phenomena that are inconsistent with the current model of the atomic nucleus.

Radioisotope–electron scattering experiments in which electrons collide with unstable nuclei are indispensible in establishing the ultimate model of the atomic nucleus, which will yield a comprehensive understanding of both stable and unstable nuclei. Wakasugi and his colleagues are taking unique approaches to achieve this world-first experiment.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
