From what I understand, both types of electrons interact via the weak force (maybe only via neutral current) and leave in the same direction. I still don't quite understand how these eletrons are 'helically polarised'. Is it something to do with their intrinsic spin?

Thanks for all your replys. Just to clarify, the reference to helical electron polarisation: produced by circularly polarised laser light on a gallium-arsenic photocathode.

In what manner can an electron be said to be helically polarised? :confused: I have heard of spin-polarisation, but that should be strictly up or down shouldn't it?
