Hantaro Nagaoka (長岡 半太郎, Nagaoka Hantarō, 19 Ağustos 1865 – 11 Aralık 1950) Japon fizikçi ve Meiji döneminde Japon fiziğinin öncüsü.
Hayatı
[değiştir | kaynağı değiştir]Nagaoka, 19 Ağustos 1865'te Japonya'nın Nagazaki kentinde doğdu ve Tokyo Üniversitesi'nde eğitim gördü. 1887'de fizik bölümünden mezun olduktan sonra Nagaoka, konuk bir İskoç fizikçi Cargill Gilston Knott ile manyetizmanın erken sorunları, yani sıvı nikeldeki manyetostriksiyon üzerinde çalıştı. 1893'te Nagaoka, Berlin, Münih ve Viyana üniversitelerinde eğitimine devam ettiği Avrupa'ya gitti. Orada aldığı Satürn'ün halkaları üzerine dersler ve Ludwig Boltzmann ile Kinetik Gazlar Teorisi üzerine bir kurs, Nagaoka'nın daha sonraki işlerinde yansıyacaktı. Nagaoka, 1900'de Paris'teki Birinci Uluslararası Fizikçiler Kongresi'ne katıldı ve burada Marie Curie'nin Nagaoka'nın atom fiziğine olan ilgisini uyandıran radyo

Nagaoka’s atomic model and hyperfine interactions
Abstract
The prevailing view of Nagaoka’s “Saturnian” atom is so misleading that today many people have an erroneous picture of Nagaoka’s vision. They believe it to be a system involving a ‘giant core’ with electrons circulating just outside. Actually, though, in view of the Coulomb potential related to the atomic nucleus, Nagaoka’s model is exactly the same as Rutherford’s. This is true of the Bohr atom, too. To give proper credit, Nagaoka should be remembered together with Rutherford and Bohr in the history of the atomic model. It is also pointed out that Nagaoka was a pioneer of understanding hyperfine interactions in order to study nuclear structure.
Keywords: Nagaoka-Rutherford-Bohr atomic model (N-R-B model), the origin of hyperfine interactions
1. Introduction
Hantaro Nagaoka was a distinguished Japanese physicist living in the early 20th century. He was a member of the Japan Academy from 1906, and assumed its presidency after receiving the Order of Culture in 1937. He is so famous that there is supposed to be nothi
