Muonic Atoms. I. Dynamic Hyperfine Structure in the Spectra of Deformed Nuclei

Precise measurements, using a stable high-resolution Ge(Li) spectrometer, have been made of the K(2p-1s) and L(3d-2p) muonic x-ray spectra for nine deformed even-even nuclei: ¹⁵⁰Nd, ¹⁵²Sm, ¹⁶²Dy, ¹⁶⁴Dy, ¹⁶⁸Er, ¹⁷⁰Er, ¹⁸²W, ¹⁸⁴W, and ¹⁸⁶W. From these measurements, parameters describing the nuclear charge distribution have been determined. Nuclear-polarization corrections have been included in the analysis. The accuracy of the determination of the parameters of the nuclear charge distribution is limited by theoretical rather than experimental uncertainties. Isotope shifts have been determined and compared with optical and electronic x-ray results.
