Abstract: The collectivity of the odd-mass nucleus

Ni was explored via intermediate-energy Coulomb excitation
using a powerful combination of particle and

-ray spectroscopy. A

is interpreted to deexcite a member of the core-coupled quintuplet 2

for this state. Both assumptions lead to a transition strength higher than predicted by a large-scale
shell-model calculation using the GXPF1 effective interaction and exceed the value predicted within a simple
weak-coupling approach
