The ground state hyperfine splitting of87Sr+ was measured with a precision of 1×10−8. The experiments were performed with an RF ion trap connected to an ISOL (isotope separator on-line), where all the possible transitions between Zeeman sublevels

Hyperfine Interactions. 74:41-46
With an RF-trap connected to an Isotope Separator On-Line (ISOL), we aim to study nuclear magnetic properties of nuclei far from stability through the hyperfine interaction by a laser-microwave double-resonance method. As a first step, the hyperfine

Radiation-detected optical pumping in solids has been developed to investigate the structure of unstable nuclei. Appreciable nuclear polarization of implanted or doped unstable-nuclei in a host crystal is achieved with the optical pumping in solids.

An on-line system of optical pumping in solids for the study of unstable nuclei was developed. The system is operated in connection with mass separators on line. The mass-separated unstable isotopes are implanted into a host crystal set at the focal

As packet-based traffic in the metropolitan area network continues to exponentially increase, and as content and applications become more distributed, conventional metropolitan area networks fail to function efficiently. Sprint Advanced Technology La

Future Internet technologies will cause an evolution in metropolitan area networks throughout the following decades. To keep pace with the development of Internet access technologies and devices, we have created a novel architecture called HORNET. Th
