Spin of a magnetic monopole

    Hi there,

    I was wondering what is the spin of a magnetic monopole. To be specific, I mean the 't Hooft-Polyakov monopole in the Georgi-Glashow model. Sure, it is a purely classical object and as far as I know, there is no known way how to fully quantize it. So, strictly speaking, the notion of spin makes no sense here. But anyway, were it quantized, aren't there any arguments for what spin it would have?

    Furthermore, the 't Hooft-Polyakov monopole has the winding number n=1. Considering solutions with higher n, would there be any n-dependence of the spin? For instance, couldn't be the spin proportional to n?
