This book was released on 1959 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic-beam magnetic resonance techniques were used to measure the nuclear spins of I/sup 123/, I/sup 124/, I/sup 126/, I/sup 130/, I/sup 132/, I/ sup 133/, I/sup 135/, and At/sup 211/. Also, measurements of the magnetic-dipole interaction constant, and the electroquadrupole interaction constant, and the electroquadrupole interaction constant for I/sup 131/ and I/sup 132/ are reported. The design of the atomic-beam apparatus is described. Experimental methods and sample preparation are discussed and results are interpreted in the light of the single particle shell-model theory of nuclear structure. (J.R.D.).

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resonant ionization laser ion sources are applied worldwide to increase purity and intensity of rare isotopes at radioactive ion beam facilities. Especially for heavy elements the laser wavelengths required for efficient resonant laser ionization are not only element dependent, but also vary to small degrees from isotope to isotope. Since the first operation of an actinide target at ISAC-TRIUMF in 2008, the demand for neutron-rich isotopes far away from stability has steadily increased. Those isotopes often have very low production rates so that often only a few ions per second are released. In order to study isotope shifts and hyperfine structure of silver, actinium and astatine, in-source resonant ionization spectroscopy in combination with radioactive decay detection has been applied. Despite the Doppler limited resolution, it has the advantage that it is ultra-sensitive and the atomic spectrum for the nuclear ground and isomeric states can be investigated individually. An isobaric separation has been demonstrated for 115-119Ag, where the hyperfine structure of one state showed a splitting of 22 GHz to 38 GHz while for the other state only a single peak spectrum can be resolved. For astatine and actinium, the main interest is to measure and study the optical isotope shift, which is for the first excitation step for neutron-rich isotopes in the order of IS_FES≈±3.7GHz/u for both elements, as these observables give insight into nuclear moments and shape. In addition, also the isotope shift of the second excitation step for astatine has been measured to IS_SES,At≈-1.7GHz/u. Laser spectroscopy on astatine has mainly been performed on the neutron-deficient isotopes 199,205At due to high count rates and low isobaric contamination. With the results obtained it is possible to extrapolate the required wavelength for ionizing and delivering the isotopes 221-225At which are of interest to e.g. electric dipole moment studies.

This book was released on 1963 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The atomic-beam magnetic-resonance flop-in technique was used to determine the hyperfine-structure separations and the hyperfine-structure anomaly between the isotopes Li/sup 6/ and Li/sup 7/; this technique was also used to measure the hyperfine-structure separations of the isotopes Re/sup 186/ and Re/ sup 188/. The separated-oscillatory-field method of Ramsey was used to very accurately determine the hyperfinestructure separations in Li/sup 6/ and Li/sup 7/ . The hyperfine-structure anomaly was determined using the separation values. The magnetic-dipole-interaction constant and the electricquadrupole-interaction constant were measured for the two radioactive isotopes of rhenium in the J = 5/2 ground state. Beams were produced by electron bombardment of irradiated rhenium wires. The spins of both isotopes were determined previously to be one. The nuclear moments of both isotopes were determined to be positive. An improved value for the electronic Lande g factor for rhenium was also obtained, with the result g = -1.95203(8).

Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of Chlorine, Bromine, Iodine and Astatine is a special edition that contains selected sections and addresses the needs of specialists in their respective fields. The text describes the general atomic properties of non-metals, particularly the halogens, as being the perfect series to study, both in physical and chemical terms. The book explains that the combination of the atomic properties implies excellent electronegativity values for the halogen atoms. The text also cites some behavior characteristics of halogens that are irregular, such as chlorine and bromine are similar but differ from fluorine on one side and iodine on the other. The book also compares the general methods of producing chlorine, bromine, or iodine by 1) oxidation of halide derivatives or 2) reduction of compounds of the halogens in positive oxidation states. The text then reviews the application of a complex valence theory that raises difficult questions about the bonding in halogen-oxygen molecules. The book also explains the biological behavior of astatine that accumulates in the liver or in the thyroid gland depending on the method of administration either as a radiocolloid or as a true solution. The book is suitable for molecular biologists and researchers, molecular chemists, and medical researchers.
