Abstract
Avalanche detection of a laser enhanced ionization (LEI) signal has be en studied in a resonance ionization detector (RID) cell containing me rcury vapor at room temperature. An avalanche multiplication factor of more than 8000 was achieved. The limit of detection of Hg resonance r adiation (lambda = 253.7 MI) was at the level of 0.5 quantum during th e lifetime of the excited 6(3)P(1)(0) state. Detection of radiation fr om a conventional CW Hg discharge lamp source with a signal to noise r atio of more than 10(4) has been achieved.
