Nuclear Gamma Resonance Study of Alloy Systems
The Ir-Fe and Ir-Ni alloy systems were studied over the whole composition range by means of the nuclear resonance absorption of the 73 keV y-rays of 193Jr and of the 14.4 keV y-rays of 57Fe. The magnetic hyperfine field at the Ir-nuclei in Ir-Ni alloys decreases approximately linearly with the Ir concentration from — 460 kOe at 4.2 K in very dilute alloys to zero at about 20 at.-% Ir. This beha...

متن کاملMössbauer Effect Studies of Interconfiguration Fluctuations in Metallic Rare Earth Compounds
Recoilless absorption spectra of the 21.6 keV gamma ray of IslEu in EuCu~Si2 and in EuRh2 reveal a single absorption line which has a strongly temperature dependent isomer shift. The recoilless absorption spectra in E ~ ~ L a l ~ R h 2 (0.075 < x < 0.5), Eu.125Pr.87~Rh2 and E u R h ~ ~ p t ~ (0.125 < x < 1) are composed of a few lines, many of which also exhibit strongly temperature dependent i...
متن کاملIDENTIFICATION AND CHARACTERIZATION OF 3 . 8 min ’ 34 “
The y-ray spectra of iodine fractions rapidly separated from the products of slow neutron fission of ‘% were studied. A 3.8 _tO.2 min species was found and was identified as 13’? from observations of corresponding growth in the intensities of the prominent 847 and 884 keV y-rays of 53 min I?. This isomer is analogous to the 2.9 h isomer 134mC~ and decays by the sequence 134mI (~*=8-)-& (JS=~+) ...
