| Abstract: | The half-lives of the isomers Dy and Dy ( E = 25.6 keV and T ∼ 30 ns for the former and E = 74.6 keV and T ∼ 3 ns for the latter) placed in a GdO crystal lattice at T = 300 K and surrounded by stable Dy nuclei in the composition of DyO were measured by the method of ( β-γ) coincidences in the beta-decay process Tb → Dy. Nuclei of Dy were obtained according to the chain Gd( n, γ)Gd → Tb → Dy from DyO weighted portions irradiated at the PWR-M reactor of the Petersburg Nuclear Physics Institute (PNPI, Gatchina, Russia). The T value observed for the isomer Dy was found to be correlated with the number of surrounding Dy nuclei. The presence of this correlation in Dy can be explained by the multiple resonance scattering of photons from isomer decay within the sample used. No such correlation was observed for Dy. The half-lives measured for the isomers Dy and Dy in the absence of the above environment are 29.2(1) and 3.50(1) ns, respectively. [ABSTRACT FROM AUTHOR] |
