New candidates for high spin isomeric targets


Journal Article

Experimental results of the accumulation and study of reaction mechanism of the de-excitation of high spin isomeric targets 108mAg (Jπ = 6+), 166mHo (Jπ = 7-) and 180mTa (Jπ = 9-) are discussed. Together with other isomers, such as 178m2Hf (Jπ = 16+), 186mRe (Jπ = 8+), 242m Am (Jπ = 5-), which can be produced by neutron-capture reactions or in reactions involving heavy ions, they can possibly be used for new experiments in nuclear physics. The large integral cross section for neutron capture (usually some barns) and enough cooling time allows the ground state of these isomers to completely decay due to their short half-life. The large integral de-excitation cross section (more 10 mb MeV) in inelastic γ-quanta scattering allows for a successful measurement on a small number of atoms ( < 1015) and makes them candidates for γ-laser on the nuclear levels. © 1999 Elsevier Science B.V.
