https://doi.org/10.1007/978-1-4612-4680-0We have observed atoms consisting of a pion and a muon produced in the decay .. This represents the first observations of an atom composed of two unstable particles and of an atomic decay of an elementary particle.

Parity Violation Effects Induced by Neutral Currents in Atoms,s not questioned until the discovery of parity violation in weak interactions, following the brilliant analysis of Lee and Yang (.). In 1958, Zel’dovich (.) gave the first discussion of the possible effects in Atomic Physics of a weak electron-nucleon interaction induced by neutral currents. In part

An Optical Rotation Experiment to Search for Neutral Current Effects in Atomic Bismuth, effect in atoms. As first pointed out by Bouchiat and Bouchiat., effects of measurable size are expected in heavy atoms if the neutral weak current interaction. between electrons and nucleons has a PNC component. In our experiment, the effect of interest is an optical rotation associated with the 8

Search for Parity Non-Conserving Optical Rotation in Atomic Bismuth,ffects of observable magnitude in atoms. One of the most promising possibilities. is to look for optical rotation close to an allowed M. absorption line in a heavy element. We report here preliminary results from our experiment. on the 648 nm J = 3/2 J = 5/2 transition in bismuth. We find that the o

Review of Precision Positronium Experiments,ted by this exotic atom containing antimatter, but also because in some ways positronium being the lightest of all atoms is also in principle the simplest to interpret theoretically. The measurement of the structure of simple atoms provides one of the best opportunities for testing the predictions o
