made my day..I tried this and it did not work at all. After two or three tries, it hit me -- no, it does not work for contact printing. I felt pretty silly.
Is it really residual aberration or just plain dirty glass? Given that both those lenses are from manufacturers regarded as either extremely good or world class (Angenieux) I'd be more inclined to wonder how they'd behave after a thorough & meticulous clean, not least because oil/ dirt that has leaked on to the elements in small quantities would probably give similar results to what you describe. What aperture are you using them at anyway?
It might be hard to wash off just the anti-halation dies/layer, without washing out the other things that come out with a pre-wash, and are there for other purposes.I have often wondered what would happen if one washed off the anti-halation layer of a film
These days the technique is mainly used at the taking stage by film cameramen:

anti-halation layer
If you can get hold of a film that has no anti halation layer then that is the answer. The sadly missed Kokak high speed IR film was such a type and the glow was one of the characteristics. I think one of the Rollie films, also IR sensitive also can produce the same effect.
