	abstract = {In previous papers [Phys. Rev. A 50, 4743 (1994); 54, 4815 (1996)] a theoretical description of the signals associated with the muon spin relaxation of simple muonated gaseous radicals has been presented. These gaseous radicals were assumed to have been formed during the slowing down process of the muons in the gaseous target and assumed to be stable chemical species at the initial observation time. The observed signals were attributed to these stable radicals. In this paper the theoretical description is extended to include situations where the radicals are formed in slow processes as opposed to fast processes with the assumption that the muon exists as muonium at the initial observation time. This muonium then reacts for the time duration of the experiment, which is limited by the muon{\textquoteright}s lifetime. The theoretical treatment is based on an operator expansion of the spin density operators for muonium and for the molecular radicals whose time dependences are described by a set of coupled linearized quantum kinetic equations. Relaxation of the signals is due to two effects, namely, the chemical reactions themselves and the collisions that reorient the molecular radical{\textquoteright}s rotational angular momentum. This affects the muon{\textquoteright}s spin via intramolecular couplings between the muon{\textquoteright}s spin, the radical{\textquoteright}s free-electron spin, and the radical{\textquoteright}s rotational angular momentum. The coefficients of the radical{\textquoteright}s spin Hamiltonian, the collisional reorientation lifetimes (cross sections), and the chemical reaction rates may be used as fitting parameters to describe the experimental signals. These could also be calculated from first principles. [S1050-2947(98)00212-1].},

	abstract = {Evidence for the formation of NeMu*, an isotopic analog of the Rydberg molecule NeH*, has been obtained from the observation of chemiluminescent emission in the near-infrared region. This is the first spectroscopic detection of a muonium-containing molecule. NeMu* was formed by stopping a 4 MeV muon (mu(+)) beam in a target vessel containing 1-6 atm of Ne and. similar to 1 Torr Ar. The wavelength spectrum of the emission, from similar to 680-1000 nm, was measured, using a variable-wavelength filter, with a resolution of +/-12.5 nm. Lower resolution spectra were also taken with a series of long pass filters. A complete histogram of photon events vs time was collected for each wavelength. Two strong transitions are observed, centered at 818 and 943 nm. Identification of NeMu* was made by a comparison of the experimental spectrum with a simulated spectrum based on detailed ad initio calculations, extended to higher excitation levels than had heretofore been reported. Both experimental and theoretical results are reported here. Although the mechanism by which the emitting states in NeMu* are formed remains unclear, radiolysis effects appear to play a dominant role, indicating that NeMu(+) (the product of muon thermalization in Ne) undergoes charge exchange with metastable Ar* and/or is neutralized by a spur electron, both species produced during the slowing down of the high energy muon.},
