Abstract

A new gadolinium isotope decaying by electron capture with a 29-hour half-life was found. Its mass number was determined to be 147 by examination of its excitation function for production by alpha particle bombardment of Sm2147O3. The electron-capture isotope Gd149 was also studied, and its half-life was redetermined to be 9.3 ± 0.3 days. The conversion-electron and photon spectra of Gd147 and Gd149 were studied. Relative photon and electron intensities were determined for some of the transitions, and some coincidence measurements were made. From the data a few multipolarities are assigned and partial decay schemes are suggested.
