Are you sure? Even if it very small, if a particle enters it's gravity well, it will be accelerated. After all the very definition of a black hole is a gravity well that has an escape velocity greater than the speed of light. Typically, a body will accelerate a smaller falling body to or near it's escape velocity unless it has a vector in a different direction. The return of the Apollo spacecraft is an example in the macroworld as they were close to the Earth's escape velocity when they re-entered the atmosphere.

Is this not true, even on the very small scale? Now, I imagine that a capture virtual particle of the pair that leds to Hawking radiation will not be so accelerated as musch it "cheats" by coming into existence so close to the Schwarzschild radius.

Even the effect of the Earth's gravity has been measured on neutrons -

is not the article I read on it in Scientific American but is yet another example, one that is online.
