Researchers diffract a beam of organic molecules

Phys.org  July 22, 2020 Physicists theorize that wave-particle duality is a fundamental feature of the universe. This suggests that all matter should have wave-like phenomena, that is, it should be able to behave similar to light and electrons. An international team of researchers (Austria, Germany) created a Bragg grating using standing light waves generated by retroreflecting a green laser from a mirror. In two separate experiments, they sent beams of the antibiotic ciprofloxacin and the dye phthalocyanine through this grating. Both experiments produced diffraction patterns with two peaks, corresponding to groups of molecules with a large momentum difference between them. […]
