What are Octupole correlations?

[Cmertin]

I'm looking through my professors research articles and he has stuff on Octupole correlations for certain elements. I'm not sure what they are, so I did a Google search and it only comes up with more research articles about people doing their own research with Octupole correlations for different elements, which after looking through them they did not describe what they are. I also tried Scholar.Google.com with no luck either.

Would anyone be able to help me with this?

Can you post your professor's research article on Octupole correlations? This might hlep us to answer the question because "Octupole correlations" could mean different things in different contexts.

Here is one (http://www.phy.anl.gov/gammasphere/pub/2005/ANL/PLB_Zhu.pdf) I know it starts off with their role in this research article, but I don't know what it means by that, and that only tells me their purpose, not what they are.

Did you read the references? Particularly reference 3, which is to a review article?
