Hardcover. Condition: Very Good. HAHN, Otto and Lise Meitner. "Die Muttersubstanz des Actiniums, ein neues radioaktives Element von langer Lebensdauer." in Physikalische Zeitschrift, 1918, volume XIX, No. 10, pp 208-218. Offered in the full issue of pp ii, (201)-224, iii-iv. The following also included in the same volume XIX, 556pp. The second half of the book has a paper stock of inferior quality to the earlier months, as is common with the Physikalische Zeitschrift in the postwar years. There is so much of interest, including three papers by Schroedinger with two responses by Einstein, as well as numerous other interesting articles. +++ Offered with: SCHROEDINGER, Erwin. "Notiz über die Ordnung in Zufallsreihen , pp 218-220, same issue. And also with a good opening paper by Arthur Korn, Mechanische Theorien des elektromagnetischen Feldes . .Hahn and Meitner in 1917 discovered the most stable isotope of the element 91, which they named protactinium (the original discoverers of this element, Fajans and Göhring in 1913, had named their short-lived isotope brevium). This parent of actinium helped resolve the uncertain sequence in the actinium series, although recognition that it was entirely independent of the uranium series (descended from U238) did not come until the discovery of actinouranium (U235) (the existence of which was inferred from Aston s mass-spectrographic work in 1929), the ultimate source of this series. After the discovery of protactinium, Hahn believed that it descended, through uranium Y (Th231), from primordial uranium in a branch parallel with the well-known uranium series. His subsequent examination of uranium and its products turned up in 1921 a small, but persistent and inexplicable, activity in the uranium series protactinium isotope. Here was a case of branching, but not the one Hahn was looking for. He had found that the first example of nuclear isomerism, i.e., uranium Z, has the same parent and the same daughter product as uranium X2 and both these protactinium isotopes are formed by, and decay by, beta emission. But their nuclei are at different energy levels and decay with different half-lives. --"Hahn, Otto." Complete Dictionary of Scientific Biography. Vol. 6.

Condition: near Fine. Leipzig 1918. first edition. Hirzel. Hardcover large 4to. In German. Many important papers in the history of modern physics by scientists as Einstein ( articles pp. 115-116, 165-166) Otto Hahn and Meitner ( "Die Muttersubstanz des Actiniums" pp. 208-218), Schroedinger ( "Notiz uber die Ordnung" pp. 218-220; "Energie komponenten des Gravitationsfeldes" pp 4-7; "Loesungssystem" pp. 20-22), Ludwig Flamm ( "Gegenwartiggen Stand der Quantentheorie pp. 116-128) and much more. Physikalische Zeitschrift for Jan - Dez 1918. 556p. plates, line drawings. Excellent condition - Very near Fine, just some toning on on pages in second half of volume to do lower paper quality no doubt due to economic problems in Germany at the time. No owner marks. 3/4 black cloth with black and grey marbled board; mounted paper spine label with title in thick black ink. Pictures available on request. Clearly 1918 was an exciting year in the world of physics.
