The nuclides near N=28 are an important testing ground for modern nuclear-structure theory. In addition to the well-known proton and neutron shell closures at calcium-48, doubly magic calcium isotopes have also been proposed at N=32 [1] and N=34 [2]. Fragmentation of single-particle strength also gives insight into basic assumptions of the shell model, such as the nature of the mean field and...
Two-neutron transfer reactions work exceptionally well as low-spin probes into nuclei. With a distinct 0+ cross-section shape, peaking at the most forward angles, and their ability to populate a range of nuclear levels without injecting large amounts of spin into the system, they can be used to study the competing modes of excitation and shapes of nuclei at low excitation energies. The nature...
Nuclei close to 100Sn are fertile testing ground of modern theories of shell model. However, being very neutron deficient, these nuclei are still experimentally very difficult to access for their investigations (e.g. only information known on 100Sn is the half-life of its ground state). Therefore, understanding about these nuclear systems is from the study of their neighbors, which are...
In the Z=34 region of the atomic chart a pattern of shape coexistence has been observed, with oblate and prolate bands apparently coexisting and switching order as neutron number changes. With recent spectroscopic developments the question of where such an inversion occurs has been drawn into question.
A detailed internal conversion electron and gamma ray spectroscopic study of 70Se was...
A new method is proposed for fitting nonrelativistic two-body scattering data and for extracting the bound state energies or resonance parameters in the compound system that is formed during the collision. The method combines the well-known R-matrix approach with the analysis based on the semi-analytic representation of the Jost function. It is shown that such a combination has the...
A two-parameter analytical formula, based on the quantum electron-ion transport cross section, is used to describe the stopping power of ionizing particles penetrating gases, as for instance in gaseous detectors in low-energy nuclear physics. The electrons of the target are described as a free electron gas (FEG), while the electron-ion interaction is described by a phenomenological...
