Hess, V.F.;
Über den Ursprung der Höhenstrahlung / Origin of Penetrating Radiation
Phys.Zeitschr. 27 (1926) 159;

A critical review of recent work on the penetrating of "ultra-gamma'' radiation. Particular reference is made to the work of G. Hoffman, R. A. Millikan (Nat. Acad. Sci., Proc. 12. pp.48-55, Jan., 1926, and Ann. d. Physik, 79. 6. pp.572-582, April 6, 1926), and F. Behounek. (Science Abstracts, 1926, 1378. A.B.W.).
