There's always talk about Alpha and Beta Fe, and how they are different or not, but what about the other functions? Surely, logically, they too can be quadrically influenced, so that Gamma and Beta Ni are different; or Alpha and Delta Si are different. Are any of the the functions different, or are they all just the same?
I'd be interested to here from anyone, but especially the reasons why those who believe some are the same but others are different believe that.
