| Abstract: | The gamma-gamma directional correlation of the 2+′-2+-0+, 913(Iγ=1.69)-934(Iγ =100)keV cascade in92Nb decay has been investigated with a NaI-Ge(Li) system. Our results yieldδ=?0.013 ?0.024 +0.041 . This is one of a very few cases where the second 2+ to first 2+ transition is not predominatelyE2. This may be related to the closed neutron shell, as earlier suggested. [Radioactivity92Zr; measuredγ-γ(θ), deducedδ] |
