Description
With the advent of relatively high-energy resolution (around 2-3 %) fast scintillators the use of fast timing techniques has had a revival in the past two decades, and led to a large number of efforts in instrumentation and development of techniques in almost all laboratories for nuclear spectroscopy. This includes stable beam facilities as well as the most advanced rare-isotope facilities.
In this presentation i will not even try to cover all these efforts, but will focus on a few points and more or less recent examples on measurements of the lifetimes of low-lying excited states, and how these (potentially precision) data can impact nuclear structure research.
Nowadays widely-accepted methods to analyze fast timing (or formerly called fast-electronics szintillaion timing [FEST]) data have been developed into a new "standard", e.g., with the introduction of the generalized centroid-shift method and ways to deal with so-called "time background". The latter can pose a huge challenge and needs to be dealt with, generally, case by case. Examples from a very low statistics data set, as well as a very high statistics set will be given, offering different ways (or besser necessities) for background considerations.
