Yes, you would still get an interference pattern. That is, the
(same) interference pattern is still there even at *arbitrarily low*
intensities (&& correspondingly long exposure times). I posted a
bunch of references on this to this newsgroup on 29.June.2001:
http://www.lns.cornell.edu/spr/2001-06/msg0033834.html

Here are a couple of other references:

http://www.hqrd.hitachi.co.jp/em/doubleslit.cfm
http://www.hqrd.hitachi.co.jp/em/movie.cfm, number (2)

The first link describes a double slit experiment using a very low
emission electron gun.

But are there experiments of good standing that directly rule out any memory of past events in the detector, e.g. with hours between single events, thermal randomization between events, or the like?

I think that that, not single particle at a time, was essentially what the OP (drspeg <drspeg@xxxxxxxxxxx>) asked.

The reference list directly provided by Jonathan didn't seem to provide any such reference, and in fact, of the four URLs listed in that article, the three last URLs didn't work (probably moved).

And although there were many follow-ups to the posting that Jonathans's was a response to, all of these claiming an abundance of experimental evidence, not one provided a reference to such an experiment. The closest was perhaps <url: http://www.ati.ac.at/~summweb/ifm/experiment/resultsf.html#top>. But seemingly also that that was just another statistically-one-at-a-time experiments.

Thus, my curiosity is pickled[1]! ;-)
