The Atomic Collision Society of Japan (ACSJ)
The Atomic Collision Society of Japan (ACSJ) is an academic organization established in 1976 with a history more than 40 years. The aim of ACSJ is the promotion of research on atomic collisions and related fields in Japan, as well as facilitating international exchange and contributing to academic and cultural development. Originally, this society was established as Atomic Collision Research Association, and the name was changed to the Atomic Collision Society in 2012 in order to clarify the spirit of establishment and contribution as an academic organization.
As of 2024, the society has approximately 300 members, engaged in scientific fields covering:
- atomic collisions,
- atomic and molecular physics,
- astronomy and astrophysics,
- radiation chemistry,
- radiation physics,
- laser physics,
- synchrotron radiation,
- quantum optics and electronics,
- atomic collisions in solids,
- molecular beams,
- chemical reaction,
- interdisciplinary research related to nuclear physics,
- exotic atoms and molecules containing positron / muon / antiproton,
- plasma physics,
- ultrasonic waves / shock waves,
- discharge phenomena,
- biological / medical applications, etc.
Our activities are:
- 1) issuing a periodical electronic academic journal in Japanese, “SHOTOTSU”
(a Japanese word meaning “collision”)
The contents include:
- Original review articles
- Announcements of seminars and conferences
- Job information
- Introduction of new members
- 2) delivering information on conferences, workshops and seminars
as well as job offers for researchers in the relevant fields
- 3) holding regular academic research meetings: annual meetings in summer
and atomic collision seminars for young scientists and students in spring
