Finite size effects on kaonic pasta structures

Non-uniform structures of mixed phases at the first-order phase transition to charged kaon condensation are studied using a density functional theory within the relativistic mean field model. Including electric field effects and applying the Gibbs conditions in a proper way, we numerically determine density profiles of nucleons, electrons and condensed kaons. Importance of charge screening effects is elucidated and thereby we show that the Maxwell construction is effectively justified. Surface effect is also studied to figure out its effect on the density profiles.

Present Status of Research on Intermediate Energy Nuclear Data.

Present status of a research on intermediate energy nuclear data, which are required for various applications, are reported. As an important foundation for data evaluation at intermediate energy region, nuclear reaction theories and models such as the preequilibrium model, intranuclear cascade model, quantum molecular dynamics, optical model potential and fission model, are reviewed. The model calculation codes are having been developed based on these theories and models. Status of these codes and results of a few benchmark tests are also described as well as the status of production of evaluated intermediate energy nuclear data files and improvement of hadron transport theories.
