The standard heats of formation for gaseous xenon tetrafluoride and xenon difluoride and the average strength of the bonds in these molecules have been determined from appearance-potential data ...

Figure 1: Steps for harmonic generation. Although we have successfully predicted the observed HHG spectrum in xenon, it is not obvious that the 4d channel will be phase matched, a necessity for HHG.

In this article, we take a look at the fundamentals of mass spectrometry, how it works, variations that can be used at each stage of the process and how they can be combined to suit different sample ...

In Star Trek, Mr. Spock’s hand-held tricorder can instantly tell what something is made of. We don’t have tricorders yet, but we’re getting close. Portable devices just a little too big to hold in one ...

The Role of Filters The intense line output of the xenon lamp makes the lamp differ from the solar spectrum in the range of 800-1100nm. The mismatch can be minimized using an AM 0 filter. Nevertheless ...
