After removing the boron fluoride, the di-isoheptyl-phenoxy-acetic acid formed is dried; it may be purified by distillation under reduced pressure. The tetradecyl-phenoxy-acetic acid is a lightyellow, viscous substance which distills, under a pressure of 3 mm., at 1800 C.-2400 C. The acid...
The weak interaction of neutral currents of the negative muon and a nucleus results in P -odd correlations in the one-photon 2 s → 1 s transition of light muonic atoms. If the standard electroweak model is used, the weak mixing of hyperfine components of the μ-atom 2 s and 2 p 1...
