Laser spectroscopy of the ground-state hyperfine structure in H-like and Li-like bismuth

Laser Spectroscopy of the Ground State Hyperfine Splitting in Lithiumlike Bismuth

Laser spectroscopic measurements of the ground state hyperfine splitting (HFS) in hydrogenlike heavy ions have triggered great interest because they can be used to test QED effects in extremely strong electric and magnetic fields. However, the interpretation of the experimental value is difficult because the uncertainty of the contribution of the nuclear magnetization distribution (Bohr-Weissko...

On the Structure of Metric-like Spaces

The main purpose of this paper is to introduce several concepts of the metric-like spaces. For instance, we define concepts such as equal-like points, cluster points and completely separate points. Furthermore, this paper is an attempt to present compatibility definitions for the distance between a point and a subset of a metric-like space and also for the distance between two subsets of a metr...

Laser spectroscopy of NiBr: new electronic states and hyperfine structure.

Laser induced fluorescence spectrum of NiBr in the visible region between 604 and 666 nm has been recorded and analyzed. Fourteen bands belonging to three electronic transition systems, namely, [15.1] (2)Delta(52)-X (2)Pi(32), [15.1] (2)Pi(32)-X (2)Pi(32), and [14.0] (2)Delta(52)-X (2)Pi(32) have been observed. Spectra of isotopic molecules were also observed and analyzed. Detailed analysis of ...

Laser spectroscopy of NiI: new electronic states and hyperfine structure.

Two new electronic transition systems, namely, the [14.0](2)Phi(7/2)-Chi (2)Delta(5/2) and the [15.7](2)Phi(5/2)-Chi (2)Delta(5/2) transitions were observed and analyzed using laser vaporization/reaction supersonic free jet expansion and high resolution laser induced fluorescence spectroscopy. In addition, the (v, 0) bands with v=6-10 of the [14.6](2)Delta(5/2)-Chi (2)Delta(5/2) transition were...
