Abstract :
The techniques used to produce a 177mLu (Jπ=23/2−,T1/2=160.4 days) target are described in this paper. Firstly, an isotopic separation of an enriched lutetium sample was used to reach a purity of 176Lu close to 99.993%. Afterwards, the high neutron flux of the Grenoble Institut Laue-Langevin reactor was used to produce the 177mLu isomer by the 176Lu(n,γ) reaction. Finally, a chemical separation was performed to extract 1013 nuclei of 177mLu. Thanks to this experiment, we have been able to estimate the destruction cross-section of the 177mLu.
