Isotope Shifts in Atomic Spectra

Pages : 215
Book Description
Atomic and nuclear physics are two flourishing but distinct branches of physics; the subject of isotope shifts in atomic spectra is one of the few that links these two branches. It is a subject that has been studied for well over fifty years, but interest in the subject, far from flagging, has been stimulated in recent years. Fast computers have enabled theoreticians to evaluate the properties of many-electron atoms, and laser spectroscopy has made it possible to measure isotope shifts in the previously unmeasurable areas of very rare isotopes, short-lived radioactive isotopes, weak transitions, and transitions involving high-lying atomic levels. Isotope shifts can now be measured with greater accuracy than before in both optical transitions and x-ray transitions of muonic atoms; this improved accuracy is revealing new facets of the subject. I am very grateful to Dr. H. G. Kuhn, F. R. S. , for having introduced me to the subject in the 1950s, and for supervising my efforts to measure isotope shifts in the spectrum of ruthenium. I thus approach the subject as an experimental atomic spectroscopist. This bias is obviously apparent in my use of the spectroscopist's notation of lower-upper for a transition, rather than the nuclear physicist's upper-lower. My reasons are given in Section 1. 3 and I hope that nuclear physicists will forgive me for using this notation even for muonic x-ray transitions.
Investigation of Short-Lived Isotopes by Laser Spectroscopy

Pages : 90
Book Description
Laser-spectroscopic methods can be applied to the systematic investigation of radioactive isotopes, covering up to 30 isotopes per element (500 nuclides in total). This book shows how the high resolution and sensitivity of laser spectroscopic methods can be used in experiments on the hyperfine structure and isotope shift of the atomic spectrum or applied to the more general problem of trace analysis. It examines the most popular methods in the field including laser spectroscopy on fast beams and resonance ionization spectroscopy, all of which have a number of variants. Techniques of production and the separation of unstable isotopes are described, along with the physics and processes of numerous laser spectroscopic methods. Also included is a summary of the results of experiments carried out on the systematics of nuclear structure in exotic regions of the nuclear chart.

Book Description
"The determination of the isotopes of various elements is of interest to scientists in many fields, particularly physics and chemistry. Improvements in the technique of measuring the relative quantities of different isotopes in a sample of an element are of particular interest now, with the large number of artificial radioactive substances which are becoming available. The most prevalent methods of determining isotopes make use of some form of mass spectrograph; but, according to modern theories of atomic structure, spectroscopic means, although more difficult in some ways, and less sensitive to traces of isotopes, may be applied without expensive equipment. With this object in view, it was suggested that a suitable form of discharge tube should be designed to eliminate any possible extraneous effects on the spectrum (such as the influence of electric and magnetic fields) and that the hyperfine structure of the spectrum of radiogenic lead be examined in an attempt to determine any isotopes which may be present.
