Popis: | Excitation of the 1049.8keV isomeric state (t1/2=11.4s, spin difference between ground and isomeric states ΔJ=8) in (176)Yb using Bremsstrahlung radiation is observed for the first time. In contrast to the photoexcitation of isomeric states in other nuclei with lower spin differences, where effective integrated cross-sections are of order tens to hundreds of barneV, an integrated cross-section of just 0.0484±0.066barneV is observed for (176)Yb. |
