1. 1. Optical lifetime studies using time-resolved spectroscopy with applications to the solar chemical composition

   Författare :Bertel Engman; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This survey presents six previously published papers dealing with time-resolved atomic and molecular spectroscopy with applications to the chemical composition of the solar atmosphere. Three methods of measuring mean lives of excited states have been used:Beam-foil spectroscopy Beam-laser spectroscopy High-frequency deflectionThe methods used to estimate the abundances of the chemical elements in the sun will also be outlined.
