Well, I make no claims as a 'heavyweight' (hey quill, how did you know I was a tad portly?), but I do know my optics *very* well, and my general science/physics grasp is ok, I guess... so here's my lightweight understanding ...
LOL, although you have mentioned it a few months back in jest

The Kerr effect...? This is something that affects polarised reflected light only. It works at a small scale and only on light reflected from certain crystalline magnetised materials by its nature. As such, I don't see any way it could cause a halo around someone. There is a related thing called the Faraday effect that refers to changes in polarised light affected by large scale magnetic fields (eg starlight as it travels across the galaxies/near to our Sun).. Problem is, that it is a quite small effect and again only affects the polarisation, not the actual amount of light.. It is difficult to see how this (or any) polarising effect could work to create a halo.
The more general Electro-Optic Effect...? That only happens within some very specific solid materials - it won't create a halo around a person in air..
But don't get me wrong - there are some relatively simple ways you can create a halo effect given a bit of creative license - ask any good theatre special effects person! I've even done it myself for some gothic-ish portraiture (no, I'm not showing you as it was for commercial use, sorry!). So I don't think you have to look for anything really exotic.. but if you want a vaguely sciency one, you could maybe assume that the person was highly statically charged, and that something (smoke/dust/gas/?) around them was being affected by that.. add a bit of back lighting and hey presto!
thanks for your opinion I am sure it will help and gives us another more informed perspective on this aspect.

Me? I think Father Gill has just conjoined his memories to a lucid dream.. or alternatively, he's like my Grandad - great at making up stories and after telling them twice or more (each time getting more dramatic) he genuinely believed the added details, or even the whole thing... RIP Gramps!
I thought it was strange you setting yourself up like that...then I read.........

I apologise if there were multiple witnesses who also *independently* verified the haloes without talking first to the good father.. I haven't really been keeping up with this thread - shame on me..
realised you would leave yourself so exposed
