Curriculum Vitae

Akito Arima, was born 1930. He is a very respected Japanese and world physicist and politician. According to his scientific discoveries, he made the list of famous physicists published in the USA involving leading physicists from the classical period (16-19 October 2010). 19th century), winners of the Nobel Prize in Physics and the narrowest candidates for the Nobel Prize. Arima performed several important functions in Japan: Minister of Education, Science, Sports and Culture; Chairman of the Parliamentary Committee on Science and Education; President of the Central Council for Education; Member of Parliament; Vice-President of the Council for The Relocation of Parliament; member of the Administrative Reform Council; President of the National Institute for Physical and Chemical Research (RIKEN); Rector of the University of Tokyo, etc. He is the holder of many distinguished international awards: Knight Commander of the British Empire; officier dans l’ordre national de la Legion d’Honneur, France; Japan Academy Prize; Bonner Prize of American Physical Society, USA; Wetherill Medal- The Franklin Institute, USA; Der Netherlandse Canselarium, Orden’ Gravenhage, Amsterdam; Order Das Grosse Verdienstkreuz, Germany; Nishina Memorial Prize, Japan; Humboldt Award, Germany, etc. He is an honorary doctor of several world universities: University of Glasgow, UK; Drexel University, USA; University of Science and Technology, China; State University of New York at Stony Brook, USA; University of Birmingham, UK; Beijing University China; University of Surrey, UK; Weizman Institute of Science, Israel; University of Stellenbosch, South Africa; University of Arizona, USA; University of Groningen, The Netherlands; etc.

Prof. Arima has published 186 CC scientific publications in physics in the world ‘s top scientific journals. The most important of Arima’s scientific discoveries are as follows:

1) The discovery of the famous “Arima-Horie Effect” which is crucial for understanding nuclear magnetic moments. This discovery is based on many subsequent investigations of magnetic moments in the world.

2) Gamow-Teller transitions and tensor correlations. Arima ‘s idea of mixing configurations is considered one powerful concept in theoretical nuclear physics.

3)For the first time in history, he calculated in the scaly model the structure of some nuclei in the sd-area.

4) He developed a low-bonding scheme for nuclear models.

5) He discovered a pseudospine for atomic nuclei.

6) In collaboration with an American physicist, he developed the Interfering Boson Model (IBM), which became one of the standard models of nuclear structure and was generalized in other fields of physics and chemistry.

Arima is also one of the world’s leading Haiku poets and winner of the Prize of Haiku Society. Arima maintained friendly and scientific ties with Croatian physicists for many years and showed affection for Croatia. He was elected as a correspondent member of the CASA in 2004.
