  • The scintillation of CF4 and its relevance to detection

    1995-1-30The emission of CF4 is mostly attributed to the excited (CF,)* and (CF,)* fragments [9]. Except for some recent measurements at atmospheric pressure [6], all other studies refer to very low pressures, in the mTorr region. CF4 was also considered in a gas scintillation chamber for the study of fission fragments [10].

    The occurrence of CF 4 and SF 6 in natural fluorites (CaF 2) is reported.Contents are found to be typically 200–2000 ppt‐mass for CF 4 and 50–100 ppt‐mass for SF 6.CF 4 and SF 6 were also detected in granites where fluorite is an accessory mineral. CF 4 and SF 6 thus possess a large reservoir in the continental crust that by
