Nuclear Physics for Rare Isotopes

Rare isotopes in the cosmos

© 2008 American Institute of Physics, S-0031-9228-0811-020-1 Radioactive nuclei with extreme neutron-to-proton ratios—rare isotopes—often decay within fractions of a second. Typically, they are not found on Earth unless produced at an accelerator. Yet nature produces copious amounts of them in supernovae and other stellar explosions in which the rare isotopes, despite their fleeting existence a...

Radioactive isotopes in solid state physics

mass separation ISOL-principle ial. Then these isotopes can be either diffused or implanted into the material under study. The most versatile procedure is ion implantation: Depending on the implantation energy, the concentration of dopants, their lateral and their depth distribution can be controlled easily. Any unwanted co-doping by other elements is only determined by the purity of the ion be...

the first importance. Behnke has demonstrated that the "lean body mass," since it represents the active tissue of a person, is superior to reference standards hitherto proposed for the estimation of physiological functions such as the masses of various organs and tissues and the volumes of the different fluid compartments in the body. In the present article, which has been reprinted as a short ...

Characterization of low, medium and high energy collimators for common isotopes in nuclear medicine: A Monte Carlo study

Introduction:In an ideal parallel-hole collimator, thickness of septal material should be sufficient to stop more than 95% of incident photons. However, some photons pass the septa without interaction or experience scattering before they reach the detector. In this study, we determined different contribution of collimator responses consist of geometrical response, septal penetr...
