Have interference on single particles been mapped

[Martyn Arthur]

Interference (trying to measure) single "particles" in a double slit experiments causes them to discontinue wave like behaviour and perform as "particles".
Has the consequence of a series of interference with single "particles" been mapped when they arrive at the detector, and does any such mapping demonstrate that a series of interfered with particles still arrive demonstrate a pattern of arrival in the form of a wave.

First of all, you know need to get it out of your mind that quantum particles behave either as classical particles or waves. They behave as quantum particles. Quantum particles have some properties that we would typically associate with a classical particle and some properties that we would typically associate with a classical wave and those properties will be more or less pronounced depending on the experimental setup that you have.

That being said: Yes, you can do single-particle interference experiments and yes they do exhibit exactly the expected interference pattern.

Thanks for the explanation but why is this marked n/a

Although this thread is a question about quantum mechanics, it had been posted in the relativity forum.

The mentors moved it from there to the quantum mechanics forum where it belongs, leaving a forwarding link on the relativity forum. The board software marks these forwarding links with a "N/A" and that's what you're seeing.

Here's an example:
