Three-dimensional nuclear chart; Understanding nuclear physics and nucleosynthesis in star

Koura, Hiroyuki   

Three-dimensional (3D) nuclear charts with toy blocks, which represent the atomic masses per nucleon number and the total half-lives for each nucleus in the entire region of the nuclear mass are constructed. The bulk properties of the nuclei can be easily understood by using these charts. These charts have been used in outreach activities for the general public and high school students. As an example, an application for a lecture of nucleosynthesis in star is introduced, some explanations that the reason for abundance of the iron, origin of uranium, etc, on planet Earth are given with the 3D chart.
