Feeding of nanosecond isomers populated in the 176Lu(n,g) reaction
The aim of the proposed experiment is to obtain a more complete nuclear level structure of 177Lu, especially at high excitation energy and paths to isomeric levels (with lifetimes from ns to µs). We want to use our pure target of 176Lu (99.995%) to avoid contamination from other capture reactions. The (n,g) reaction at thermal energy where the capture cross-section is around 2000 b will allow to obtain a good statistics. The use of the new FIPPS array combined with our LaBr3 array will allow us to get g-g-coincidences for g-g-spectroscopy analysis and to perform fast-timing to measure nuclear lifetimes greater than few hundreds ps. All these characteristics found only at ILL will make a unique opportunity to address our problem.
