Half a gram – a thousand lives

The article presents information on the latest drug policy change in the Russian Criminal Code: a decrease of the drug threshold amounts for which possession can lead to a criminal liability. Also, the article presents an assessment of the 2003-2004 liberal revisions in the Criminal Code, and an analysis of the background/premise for the 2006 counter-reform. The author examines the new criteria...

Nuclear Binding and Half-Lives

Nuclear Forces. Protons give the nucleus of an atom a net positive charge. So, why doesn’t the nucleus explode? Nuclear stability is possible because the particles in the nucleus are each tiny magnets, and magnets can be arranged to attract one another. When the particles inside the nucleus have specific locations, the forces from electrical charge can be in balance with the magnetic forces fro...

Shell - model half - lives for r - process N = 82 nuclei

We have performed shell-model calculations of the half-lives and neutron-branching probabilities of the r-process waiting point nuclei at the magic neutron number N = 82. These new calculations use a larger model space than previous shell model studies and an improved residual interaction which is adjusted to recent spectroscopic data around A = 130. Our shell-model results give a good account ...
