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).

- Comment: Possibly notable, but the sources aren't sufficient for satisfying WP:GNG, and it's not entirely clear whether and how this satisfies WP:NACADEMIC (I'm thinking criteria #1 and/or #7 look likely candidates, but we would need to see clear evidence to support that).

Arne Claes Olof Johnson (1944-2023) was a Swedish nuclear physicist most known for the discovery of the 'backbend',[1][2] a phenomenon described in ref.[3] Johnson became instrumental in the development of large detector arrays like Nordball[4] and EUROBALL.[5] He was professor in nuclear physics at the KTH Royal Institute of Technology.[6]
Bibliography
editArne Johnson studied engineering physics at KTH Royal Institute of Technology from 1963 to 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)[3] during his PhD research. 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][3] The irregularity was interpreted at that time as a phase transition[3] which also became the title of Arne Johnson's thesis 1973, "Evidence for phase transitions in deformed nuclei".[7]
Together with the theoretical nuclear physicist Zdzisław Szymański, the emerging field of nuclear rotational states (see also rotational spectroscopy) was described in a review paper.[8] Arne Johnson received the academic title of a Docent in 1974 (see Academic ranks in Sweden), appointed adjoint professor at KTH Royal Institute of Technology in 1986 and full professor in nuclear physics in 1997.[6] He was honoured with the Borelius medal for his achievements in physics and as dean of the engineering science faculty at KTH.[9]
