High spin states in176, 178Re have been studied using in-beam γ and e? spectroscopy techniques through heavy ion induced fusion reactions. A ΔI=2 rotational band of doubly decoupled type has been identified in each isotope. 相似文献

Coprecipitation leads to self-assembly of bioactive DNA on the surface of salt, sugar or amino-acid crystals and provides a rapid inexpensive immobilization method suitable for preparing dry-powder formulations of nucleic acids, useful for storage, imaging and drug delivery. 相似文献

Four new ternary carbometalates of the general formula RE2[Mo2C3] with RE = Ce, Sm, Tb and Dy have been prepared by a high temperature synthesis route. The Ce, Tb and Dy compounds crystallize isotypic to Er2[Mo2C3], Sm2[Mo2C3], however, is an isotype of Ho2[Cr2C3]. The crystal structures comprise polyanionic layers [(Mo2C3)6?] with the rare‐earth metal ions in between. The layers are constructed by edge and vertex connected MoC4 tetrahedra, which display strong covalent Mo–C bonds. The compounds show metallic behaviour close to the classical limit of 100 μΩ cm for metallic conductors. The magnetic properties are quite different, however they are consistent with the presence of trivalent RE3+ ions with the exception of Ce2[Mo2C3], which contains nonmagnetic Ce species. Electronic structure calculations reveal that the additional electron mainly populates the Ce partial structure. The title compounds extend the series of known carbomolybdates RE2[Mo2C3]. The late lanthanides Gd, Tb, Dy, Ho, Er, Tm, and Lu with comparatively small RE3+ ions and Ce as Ce4+ adopt the Er2[Mo2C3] structure type, whereas the early lanthanides Sm and Pr with larger RE3+ ions crystallize in the structure types of Ho2[Cr2C3] and Pr2[Mo2C3], respectively. 相似文献

A model has been investigated describing a situation in which two noninteracting high-j Nilsson-BCS quasiparticles move in the deformed field of an axially and reflection symmetric rotor. According to the positions of thej-shells with respect to the proton and neutron Fermi surfaces structures of different character emerge referred to as semi- and doubly-decoupled. In particular, strongly Coriolis-distorted bands recently reported in doubly odd Tl nuclei are discussed. Also \(\tilde \pi h_{9/2} \) bands in neighbouring odd mass Tl isotopes are analysed on the same footing. It is shown that the pronounced odd even staggering of the transition energies can be understood as a specific quantal feature associated with the Coriolis interaction. 相似文献

Excited states of220Ac have been investigated by means of the209Bi(14C,3n) reaction and using the “Château de Cristal” gamma ray facility. The observation of bands with alternating parity states reveals the reflection asymmetric nuclear shape of220Ac. The extracted B(E1)/B(E2) ratios display a clear spin dependence. 相似文献
