Electronic spectroscopy of I(2)-Xe complexes in solid Krypton.
In the present work, we have studied ion-pair states of matrix-isolated I(2) with vacuum-UV absorption and UV-vis-NIR emission, where the matrix environment is systematically changed by mixing Kr with Xe, from pure Kr to a more polarizable Xe host. Particular emphasis is put on low doping levels of Xe that yield a binary complex I(2)-Xe, as verified by coherent anti-Stokes Raman scattering (CAR...
متن کاملMuonium Decay
Modifications of the μ+ lifetime in matter due to muonium (M = μ+e−) formation and other medium effects are examined. Muonium and free μ+ decay spectra are found to differ at O(αme/mμ) from Doppler broadening and O(αme/mμ) from the Coulomb bound state potential. However, both types of corrections are shown to cancel in the total decay rate due to Lorentz and gauge invariance respectively, leavi...
متن کاملLocalization of Left-to-right Shunts by Radioactive Krypton.
In 1958 Weitzman and McAlister reported on the use of a radioactive tracer (32p) for accurate localization of the site of a left-to-right shunt in congenital cardiac lesions. The advantage of such a technique is that it can demonstrate premature arrival of the tracer in the chamber or vessel that receives the shunt. There is a clear-cut time difference due to the short circuit through the defec...
متن کاملMuonium Spectroscopy
The electromagnetic interactions of electrons and muons can be described to very high accuracy within the framework of standard theory, in particular within the hydrogen-like muonium atom. Therefore precision measurements allow to test basic interactions in physics and to search for yet unknown forces. Accurate values for fundamental constants can be obtained. Results from experiments on the gr...
متن کاملMuonium Lifetime and Heavy Quark Decays∗ (lessons Learned from Muonium)
When asked to speak at this Symposium honoring the distinguished scientific career of Vernon Hughes, I knew the word “muon” would have to appear in my title and some property of that particle would provide my theme. Indeed, everyone at Yale knows the answer to I.I. Rabi’s famous question, uttered when confirmation of the muon’s existence was announced: “Who ordered that?” It must have been Rabi...
