Nature (London)	118		The current (September) issue of the Berichte of the German Chemical Society contains a paper by Profs. F. Paneth and K. Peters on "The Transformation of Hydrogen into Helium," in which they describe in outline how they have succeeded in detecting the presence of a very minute amounts of helium, of the order of one hundred millionth of a cubic centimeter, derived from hydrogen which had been absorbed by finely divided palladium at ordinary temperature.		1926 The Reported Conversion of Hydrogen into Helium Nature (London) The current (September) issue of the Berichte of the German Chemical Society contains a paper by Profs.

Fundamental Idea of the Research The theoretical possibility of converting hydrogen into helium is always being referred to within the context of modern conceptions of Prout's hypothesis, in astrophysical calculations of the life of fixed stars and in radioactive considerations as to the origin of Hessian radiation. So far, however, there have been no successful attempts to bring about this transformation of elements, despite experiments with a wide variety of electrical discharges and the introduction of large amounts of energy.	helium H2, Pd, history	Paneth, F., Peters, K. 1926 On the transmutation of hydrogen into helium Ber. 1.

Nature (London)	119		A few months ago, K. Peters and I published an account of experiments we had made in an attempt to transmute hydrogen into helium (Ber. D. Deutschen. Chem. Ges., 59, 2039: 1926). A more or less detailed account of this publication appeared in the columns of Nature (Vol. 118, p. 526. 1926), and perhaps I may be permitted to refer to a more recent publication on the same topic by K. Peters, P. G?nther, and myself (Ber. D. Deutschen Chem. Ges., 60, 808; 1927). In this communication, as a result of further experiments, we feel that we are in a position to give an explanation of the occurrence of the observed very small quantities of helium in our experiments, without having recourse to the assumption of a synthesis of helium.	critique, retraction, history	Paneth, F. 1927 The transmutation of hydrogen into helium Nature (London) A few months ago, K.

It includes a Summary in English: The temperature stability of finely dispersed metaltritium systems in vacuum was investigated. The tritium content of the metals was measured by a new method based on the radio-activity of the tritium. Ways were found to prepare metal-tritium systems, sufficiently temperature-stable for technical applications. In addition, the experiments were found to be of interest in checking various classical and modern theories on the formation of hydrides.	titanium, tritium, reduced radioactivity	van de Vate, J.

Discovered by Rontgen as long ago as 1895, this type of radiation occurs when the beta-electrons from a disintegrating beta-emitter are braked in the surrounding matter, being termed "external bremsstrahlung" in this case. But in such isotopes the beta-electron is also accompanied by a type of radiation that is independent of the surrounding matter. This type is called "internal bremsstrahlung", because it is generated by the electron inside the radioactive atom, during the decay process. It was first demonstrated by Aston 1) in the "twenties" when, in the course of gamma-ray measurements on RaE, he detected a soft, inhomogeneous form of gamma-radiation.	titanium, tritium, reduced radioactivity	van de Vate, J.

It includes a Summary in English: The investigations by van de Vate, Reifenschweiler and van de Ligt into the temperature-resistant properties of finely dispersed metal-tritium systems have been supplemented by experiments on titanium-oxygen-tritium systems, mainly intended for the purposes of orientation. In these experiments both the tritium and the oxygen pressure were varied and the influence of these variations on the composition of the temperature-resistant residue was ascertained.

A great discrepancy was found between the experimental results and the theory. The experimental values of the ratio I-EBS were between four and thirty times lower than the ratio I-IBS predicted by theory. This discrepancy may be due either to the generation of characteristic x-radiation in the experimental arrangement used or to the fact that the theory is not applicable to tritium on account of its extremely low atomic number and beta-ray energy. The wide scatter in the experimental results may likewise be due to the generation of characteristic x-radiation.	titanium, tritium, reduced radioactivity	Wickenden, D.
