Director Kevin Insik Hahn
Director Hahn is a world-renowned expert in the field of nuclear physics and nuclear
astrophysics by utilizing rare isotope accelerators. Experimental nuclear astrophysics is to study
key
nuclear reactions that are responsible for generating heavy elements and explosive energy in stars
such
as the sun and supernovae. Hahn introduced the field of experimental nuclear astrophysics to the
nuclear
physics community in Korea and contributed greatly to the advancement of nuclear astrophysics
research
in Korea.
Previous to coming to IBS, he carried out many important experiments at the world's
leading
research institutes, such as Yale University, Caltech, Brookhaven National Laboratory, and RIKEN
(Japan). For the past 20 years, he has worked in experimental nuclear physics as a faculty member at
Ewha Womans University. He conducted in particular important experiments related to the breakup
reactions from the HCNO cycle to the rp-process in explosive stellar sites such as novae and X-ray
bursts. Recently, an interesting result of discovering a new magic number for neutron-rich isotopes
was
published from an international collaboration. As a part of a joint PHENIX international
collaboration,
the world's first suggestion that the quark-gluon plasma may exist in small systems was published in
the
journal “Nature Physics”.

한인식 단장은 희귀동위원소 가속기를 활용한 핵물리와 핵천체물리 분야의 세계적인 과학자다. 실험 핵천체물리학은 가속기를 이용하여 태양이나 초신성과 같은 별에서
어떤
핵반응에 의해 무거운 원소와 폭발에너지가 생성되는지 규명하는 분야이다. 한인식 단장은 핵천체물리학을 국내에 처음 소개하며 연구 활성화에 크게 기여해왔다.
미국 예일대, 칼텍, 브룩헤이븐 국립연구소, 일본 이화학연구소 등 세계 선도급 연구기관에서 연구했으며, 지난 20여 년간 이화여자대학교에서 핵물리 분야에 매진
해왔다. 특히 신성이나 엑스선버스트와 같은 폭발적인 천체 내부에서 발생하는 HCNO 사이클 breakup 반응에 대한 여러 실험을 주도적으로 수행하였다. 최근에는 보통 핵보다
중성자가
많은 희귀 핵의 새로운 마법 수(magic number)를 발견해 연구 결과를 발표했으며, PHENIX 국제공동 연구의 일환으로 쿼크-글루온 플라즈마가 작은 시스템에서도 존재할 수
있다는
것을 세계 최초로 제시해 국제 과학계의 주목을 받기도 했다.
