Submission declined on 25 August 2023 by Robert McClenon (talk). This submission's references do not show that the subject qualifies for a Wikipedia article—that is, they do not show significant coverage (not just passing mentions) about the subject in published, reliable, secondary sources that are independent of the subject (see the guidelines on the notability of people). Before any resubmission, additional references meeting these criteria should be added (see technical help and learn about mistakes to avoid when addressing this issue). If no additional references exist, the subject is not suitable for Wikipedia.

Arne Claes Olof Johnson (born 21th of June 1944) is a Swedish nuclear physicist. He is most known for the discovery of the 'backbend' [1][2] and became instrumental for the development of large detector arrays like Nordball[3] and EUROBALL[4]. He is Emeritus in Nuclear physics at the KTH Royal Institute of Technology.
Bibliography
Arne Johnson studied Engineering physics at KTH Royal Institute of Technology in 1963 -1967. After completion, he started his PhD in Nuclear spectroscopy under supervision of Sven Hjorth and Hans Ryde. He discovered irregularities in the spectrum of 160Dy(Dysprosium)[5] during his PhD research. The electronic engineer Jozef Sztarkier developed an electronic circuit such that the following experiment could indeed prove that the irregularity belonged to the same structure in 160Dy[1]. Further experiments revealed even stronger irregularities in the spectrum of the nucleus of 162Er(Erbium) where the figure of the Moment of inertia shows a 'backbend'[2]. The irregularity was interpreted at that time as a Phase transition[5] which also became the title of Arne Johnson thesis 1973, 'Evidence for phase transitions in deformed nuclei'. Together with the theoretical nuclear physicist Zdzisław Szymański[6] the emerging field of nuclear rotational states (see also Rotational spectroscopy) was described in a review paper[7]. Arne Johnson received the academic title of a Docent in 1974 (see Academic ranks in Sweden). Following international visits at a large number of leading laboratories in both Europe and the US, like the Niels Bohr Institute, Denmark, Daresbury Laboratory, England, Orsay and Strasbourg, France, GSI Helmholtz Centre for Heavy Ion Research, Germany, Laboratori Nazionali di Legnaro, Italy, and Brookhaven National Laboratory, Oak Ridge National Laboratory and Lawrence Berkeley National Laboratory, USA he was appointed adjoint professor at KTH Royal Institute of Technology in 1986 and full professor in Nuclear physics 1997.
During his military service at the FOA (Swedish National Defence Research Institute) 1977-1978, he was responsible in developing a Gamma-ray spectrometer for radioactive Xenon leaking from underground bomb test. Lateron, he initiated with Nordic nuclear physicist the development of the advanced detector system Nordball[3] and became the Swedish representative for the European detector system EUROBALL[4]. At KTH Royal Institute of Technology he was appointed to different leading positions like the Dean of the faculty of Physics, Electrical Engineering and Computer Science 1999-2004 and vice head of the school of Engineering Physics 2005-2008. He became Emeritus 2011.
