Giant-resonance studies with radioactive beams: Perspectives
No full textFirst-generation radioactive ion-beam facilities have already been in operation for some time. Advanced facilities that will deliver high-intensity radioactive nuclear beams ranging in energy from below the Coulomb barrier to up to several hundred MeV per nucleon (MeV/u) are either starting operation, or under construction or in the planning stage. In this paper the perspectives of using radioactive nuclear beams to study giant resonances in nuclei far from the valley of stability are explored. In particular, emphasis will be made on information on certain nuclear properties that can be gained from such studies
Microscopic structure of charge-exchange spin-isospin modes through decay measurements
Get PDFThe study of particle decay of charge-exchange giant resonances (CEGR) furnishes information on their microscopic structure. Furthermore, gamma decay of CEGR call help to unravel their structure. For example, the gamma-decay of the Gamow-Teller (GT) resonance to the isobaric analogue state (IAS) points to a possible method to study quenching of GT strength. The study of gamma-decay of the spin-flip dipole resonance (SDR) to GT and low-lying states will possibly allow to disentangle the different spin components. These aspects will be discussed in the light of recent (He-3,t) experiments at E(He-3) = 450 MeV and theta = 0 degrees performed to study the proton decay of CEGR in Bi-208 and N-12 and the gamma decay of the GT resonance, IAS and SDR in Nb-90
Horizon 2020: Opportunities and Perspectives
No full textOur Nuclear and Hadron Physics community has participated in the Framework Programmes (FP) of the European Commission (EC) from the early days. I will not discuss here the participation of individual scientists in person-oriented actions such as the Marie-Curie Fellowships and later the European Research Council (ERC) Starting, Consolidator and Advanced Grants, although many scientists from our community benefitted from these personal grants. I will only discuss in the following programs that offer(ed) the possibility for Nuclear Physics Research Infrastructures (RIs) and large groups to apply for collective activities
Giant resonance research: present interests and future perspectives
Get PDFIn the last decade extensive work has been done to explore and understand various giant resonance phenomena. The research involved the study of the giant dipole resonance as a function of temperature and angular momentum, the study of compressional modes - the isoscalar giant monopole and dipole resonances - and the investigation of their microscopic structures, the study of the charge-exchange modes both in the beta(+) and beta(-) directions, the establishment of the existence of double-phonon giant resonances, in particular those of the isovector GDR and the isoscalar GQR, etc.. A review of some of these advances is discussed and possible future directions in view of the operating and/or planned radioactive nuclear beam facilities will be delineated
Gebiedsontwikkeling na(ast) zware industriële bedrijvigheid
No full textIn deze bijdrage staan vraagstukken die zich voordoen rondom gebiedsontwikkeling in de nabijheid van zware industrie centraal. Vanuit juridisch en bestuurskundig oogpunt wordt ingegaan op de mogelijkheden tot (het afdwingen van) 'vergroening' van de industrie en/of de keuzes tot behoud, tot verplaatsing of stopzetten van de industriële activiteiten en wie daarover besluit. Auteurs laten zien dat verschillende rationaliteiten elk met eigen spelers, instrumenten en argumenten de toekomst van het gebied benaderen.Urban Development ManagementManagement in the Built Environmen
