See the setup in the picture. There are 2 sources who each emit a particle at the same time. And there are 3 slits, such that the particle from source1 can go through slits1&2 and the particle from source2 can go through slits2&3. There is a detector at the common slit, so slit2. The particles are identical (for example 2 photons). Was such an experiment performed ?
