Electronic Engineering majors Shota Amano and Mizuki Okubayashi win poster awards at FY2020 Symposium on Nuclear Data


During the FY2020 Symposium on Nuclear Data of the Nuclear Data Division, Atomic Energy Society of Japan, held November 26-27, 2020 at RIKEN in Wako, Saitama Prefecture, two graduate students majoring in Electronic Engineering received Poster Presentation Awards. They were Shota Amano and Mizuki Okubayashi.
Four posters were chosen from 21 submitted by student participants in the symposium. Two of the winners were submitted by Kindai University students.
Amano used dynamics modeling for theoretical calculations to conduct detailed analysis of the mechanism behind nucleon transfer reactions for nuclei in the heavy elements range. He undertook calculations for angular distribution and mass distribution of two nuclei, which originated from the incident nucleus and target nucleus during the reaction. He then compared these with experimental values to derive the correlation for the coefficient of friction of the tangential direction and of the moment of inertia resulting from the collisions.

Using r-process network calculations concerning the creation of elements in the universe, Okubayashi carried out theoretical calculations, primarily for fission for the neutron-rich nuclei of elements heavier than uranium. His research improved methods for calculating charge distribution resulting from fission of neutron-rich nuclei, an important contribution to research on the creation of elements in the universe.
