Kimiko Sekiguchi is an experimentalist of nuclear physics. My research interest is to understand the forces acting in nuclei. Particularly I am interested in clarifying the roles of three-nucleon forces (3NFs) in nuclei.

Mainly I perform experiments with my colleagues using light ions, e.g. polarized deuterons and/or protons, at RIKEN, CYRIC and also at RCNP, Osaka University.

Recent Information

  1. 1. My message was posted at the site of “People”

    of School of Science, Tohoku University (April, 2019).

  1. 2. Experiment of a polarized proton beam on our polarized 3He target

    was performed at RCNP in Osaka, November, 2018 (Spokesperson :
