Ah, that's very simple. I guess I was stuck on the fact that the matrices have multiple dependencies between them. Because of that I was fixed on showing their span was the whole space. But obviously they're linearly independent so I don't need that... Ok, thanks. ^_^

Hi all, I'm interested in proving/demonstrating/understanding why the Dirac gamma matrices, plus the associated tensor and identity, form a complete basis for 4\times4 matrices. In my basic QFT course, the Dirac matrices were introduced via the Dirac equation, and we proved various...

I've made some progress, which is essentially a reworking of the 164Er case. Rotational level spacing is of the order of 10 keV, so that's the clear candidate for the levels. I feel like I need to supplement this with an explanation of why there are so many levels, however. I'm thinking of a...

Hi all, I'm doing some test prep for a Nuclear Physics course and working on a past paper. I've attached a photo of the question. The diagram is 3.19 in Krane. The course is based on Krane, and so the relevant chapter is Chp 5: Nuclear Models. Problem description The problem is to explain...
