Gamma ray activation spectra are used by nuclear physicists to identify the elemental composition of unknown substances. Neutron bombardment causes some of the atoms of a sample to change into unstable isotopes, which then decay, emitting gamma radiation at characteristic energies and intensities, By identifying these isotopes, the composition of the original substance can be determined. GAMMA ...

Anomalous isotope shifts in the chain of light Hg isotopes are investigated by using the Hartree-FockBogoliubov method with the Skyrme SIII, SkI3 and SLy4 forces. The sharp increase in the mean-square radius of the odd mass Hg isotopes is well explained in terms of the transition from an oblate to a prolate shape in the ground state of these isotopes. We discuss the polarization energy of time-...

Neutron capture cross sections of unstable isotopes are important for neutron induced nucleosynthesis as well as for technological applications. The Rare Isotope Accelerator (RIA) or comparable facilities will be able to produce radioactive ion beams up to 10 12 particles/s and would therefore be a suitable place for (n,γ) studies on radioactive isotopes with half-lives between days and months....

We present montage, a post-processing nucleosynthesis code that combines a traditional network for isotopes lighter than calcium with a rapid algorithm for calculating the s-process nucleosynthesis of the heavier isotopes. The separation of those parts of the network where only neutron-capture and beta-decay reactions are significant provides a substantial advantage in computational efficiency....

Patients recently treated with radioactive isotopes may present problems or even hazards during physical examination, operation or autopsy, especially following the use of iodine isotopes and 198Au. 32P is rarely a significant hazard. Contamination of victims of radiation accidents may be a problem initially, but they are usually promptly decontaminated. Guidance of the hospital's radiation saf...

The Relativistic Mean Field (RMF) theory is applied to the analysis of groundstate properties of Ne, Na, Cl and Ar isotopes. In particular, we study the recently established proton skin in Ar isotopes and neutron skin in Na isotopes as a function of the difference between the proton and the neutron separation energy. We take the TMA effective interaction in the RMF Lagrangian, and describe pair...

Systematic analysis of the deformations of proton and neutron densities in even-even C isotopes was done based on the method of antisymmetrized molecular dynamics. The E2 transition strength was discussed in relation to the deformation. We analyze the B(E2; 2 + 1 → 0 + 1) in 16 C, which has been recently measured to be abnormally small. The results suggest the difference of the deformations bet...

At the Kernfysisch Vensneller Institiutr (KVI) in Groningen, NL, a new facility (TRIµP) is under development. It aims for producing, slowing down, and trapping of radioactive isotopes in order to perform accurate measurements on fundamental symmetries and interactions. A production target station and a dual magnetic separator installed and commissioned. We will slow down the isotopes of interes...
