Download Kapitza in Cambridge and Moscow. Life and Letters of a by J.W. Boag, P.E. Rubinin, D. Shoenberg PDF

By J.W. Boag, P.E. Rubinin, D. Shoenberg

The bizarre profession of the well-known Soviet physicist Peter Kapitza used to be divided among Cambridge and Moscow. In Cambridge he was once a protegé of Rutherford and whereas learning there he unfolded a brand new quarter of study in magnetism and occasional temperature physics. even if, in 1934, in the course of a summer season stopover at to the Soviet Union, Kapitza used to be avoided from returning to Cambridge and remained in Moscow for the remainder of his lengthy existence. even with many ups and downs and massive problems in his family members with best political figures within the Kremlin, he persevered to augment his medical acceptance and past due in existence was once offered the Nobel Prize.

After an introductory biographical memoir, the better a part of the booklet involves extracts from the varied letters Kapitza wrote all through his lifestyles, letters that are unusual via their eloquence, the originality of his reviews and his forthrightness. His very attention-grabbing correspondence with Rutherford and especially his many letters to most sensible political figures within the Soviet Union akin to Molotov, Stalin and Khrushchev on questions of medical and commercial coverage are all integrated during this specified record. jointly they supply a rounded photograph of a notable character who contributed loads to the medical and cultural lifetime of either England and the Soviet Union.

This attention-grabbing publication is illustrated with a powerful choice of ancient photos and may be of curiosity to technological know-how historians, to low temperature physicists and to `Sovietologists', yet chiefly the booklet should still entice the overall reader for its human curiosity. a number of the letters show his emotional reactions to the most important blows he needed to endure on a number of events, whereas others supply penetrating and sometimes fun reviews on English lifestyles and associations as obvious through a Russian, and on Soviet existence from the inside.

Download Metal Clusters at Surfaces: Structure, Quantum Properties, by Karl-Heinz Meiwes-Broer PDF

By Karl-Heinz Meiwes-Broer

Numerous experiments and calculations have proven that remoted steel clusters own many fascinating good points, fairly varied from these recognized from floor and stable- kingdom physics or from atomic and molecular physics. The technological exploitation of those new houses, e.g. in miniature digital or mechanical parts, calls for the cluster to be introduced into an atmosphere similar to an encapsulating matrix or a floor. as a result of the interplay with the touch medium, the houses of the clusters may well swap or maybe disappear. hence the physics of cluster-on-surface structures -- the most topic of this publication -- is of primary significance. The publication addresses a large viewers, from the newcomer to the specialist. ranging from primary innovations of adsorbate-surface interactions, the amendment of digital houses via electron confinement, and ideas of cluster creation, it elucidates the designated houses of the hot metal nanostructures.

Download Isotope Shifts in Atomic Spectra by W.H. King PDF

By W.H. King

Atomic and nuclear physics are flourishing yet precise branches of physics; the topic of isotope shifts in atomic spectra is without doubt one of the few that hyperlinks those branches. it's a topic that has been studied for good over fifty years, yet curiosity within the topic, faraway from flagging, has been motivated in recent times. quickly pcs have enabled theoreticians to judge the homes of many-electron atoms, and laser spectroscopy has made it attainable to degree isotope shifts within the formerly unmeasurable parts of very infrequent isotopes, short-lived radioactive isotopes, vulnerable transitions, and transitions regarding high-lying atomic degrees. Isotope shifts can now be measured with higher accuracy than ahead of in either optical transitions and x-ray transitions of muonic atoms; this more suitable accuracy is revealing new elements of the topic. i'm very thankful to Dr. H. G. Kuhn, F. R. S. , for having brought me to the topic within the Fifties, and for supervising my efforts to degree isotope shifts within the spectrum of ruthenium. I hence method the topic as an experimental atomic spectroscopist. This bias is clearly obvious in my use of the spectroscopist's notation of lower-upper for a transition, instead of the nuclear physicist's upper-lower. My purposes are given in part 1. three and that i desire that nuclear physicists will forgive me for utilizing this notation even for muonic x-ray transitions.

By Prof. Dr. rer. nat. Theo Mayer-Kuckuk (auth.)

Als im August 1845, so berichtet die Anekdote, Friedrich Wilhelm IV. , König von Preußen, die neuerrichtete Sternwarte der Universität in Bonn besuchte und den Astronomen mit den Worten begrüßte: "Na, Argelander, was once gibt es Neues am Himmel?", erhielt er zur Antwort: "Kennen Majestät schon das Alte?" Die kleine Geschichte beleuchtet ein difficulty, dem zu allen Zeiten Lernende und Lehrende gleichermaßen gegenüberstehen. Es ist deshalb die Hauptaufgabe eines einführenden Lehrbuchs, das Alte im Hinblick auf das Neue zu vermitteln. Die Zielsetzung des vorliegenden Studienbuches ist es daher, eine Übersicht über die etablierten Erscheinungen und Beschreibungskonzepte zu geben und die moderneren Perspektiven erkennbar werden zu lassen. Das Buch befaßt sich weder mit experimen­ tellen noch mit theoretischen Techniken. Der textual content beginnt zur Einführung mit der klassischen Behandlung elastischer Streuung anhand der Rutherford-Streuung. Streuprobleme werden dann im Kapitel4 ausführlicher besprochen. Die Ergebnisse dienen als Grundlage für KapitelS über Kernkräfte und Kapitel? über Kernreaktio­ nen. In den Kapiteln 2 und three werden dazwischen die wichtigsten Grundzustandseigen­ schaften der Kerne und die Bedingungen des radioaktiven Zerfalls behandelt. Die Erscheinungen des ß-Zerfalls werden als Übergang zur Physik der Elementarteilchen im letzten Kapitel dargestellt. Entsprechend der Zielsetzung des Buches wurden Gegenstände wie etwa der Durchgang ionisierender Strahlung durch Materie nicht besprochen. Sie sind zwar in der Kernphysik technisch sehr wichtig, gehören aber der Problemstellung nach in die Atom- und Festkörperphysik. Bei der hier vorliegenden ergänzten und korrigierten five. Auflage wurden die bewährte Gliederung und der Hauptteil des Textes beibehalten.
