Soddy in Trans. Chem. Soc. 115 23 We have to take into account in our analysis of matter, not only the heterobaric heterotopes before recognised, but also heterobaric and isobaric isotopes and isobaric heterotopes or isobares. 1933 F. W. Aston Mass-spectra & Isotopes xii. 158 Spectra were obtained which showed four strong isotopes and two very weak ones, one of which is isobaric with W186. 1948 S. Glasstone Textbk. Physical Chem. (ed. 2) ii. 171 With the development of the study of artificial radioactivity it has become apparent that there are more than seventy pairs of such isobaric isotopes, now known as isomeric nuclei. 1953 D. R. Inglis in Rev. Mod. Physics XXV. 395/2 One finds the states listed according to the usual quantum numbers L and S of the (LS)-coupling scheme and also according to the isobaric spin quantum number T (or isotopic spin as it has been less aptly called since it was named long ago by Wigner, who agrees to this renaming of his child). 1971 Physics Bull. Mar. 137/1 Isobaric spin was first introduced into nuclear interactions by Heisenberg purely as a mathematical convenience. < as lemmas |
