I am working on wording for a report. I need to a word to describe long ranged interaction that is constant in strength. But I am aware that people sometimes use 'long-ranged' to mean decaying strength with $1/r$. I want to describe a constant interaction strength. Any suggestions for intuitive wording?
interaction that does not depend on $r$
interaction that is independent of distance
... of these the top one would be my favourite - sounds like a pretty unusual interaction that does not depend on $r$. If I was writing I would use the top term and explain it carefully the first time as it sounds so unusual to me. - and maybe occasionally use one of the other expressions below - I agree that 'long-range' does not really fit the bill here.
