Description
The structural evolution on the far neutron-rich side of stability is critical for defining the features of the elemental abundance distribution created during the rapid-neutron capture process (r-process). A potentially large shell-gap was historically predicted at N=70 in $^{110}$Zr, which could significantly modify the r-process abundances before the A=130 peak. Recent lifetime measurements in the region suggest however that $^{110}$Zr is well deformed. We present the first direct data on the structure of this nucleus, spectroscopy of the low-lying 2+ and 4+ states, and will discuss the agreement with the available theoretical predictions.
