Abstract : Narrow UV transitions in atomic Hg can be utilized for a high quality atomic frequency standard. The primary goal of the research supported by this grant was the development of a laser-cooled source of ultracold Hg atoms and the spectroscopic study of the doubly-forbidden clock transition to better understand its potential as a future atomic clock. During this funding period a novel UV laser system was developed to efficiently cool and trap atomic Hg to temperatures below 100 micro Kelvin. The narrow 1S_0 to 3P_0 clock transition was measured and used to determine the temperature of the Hg ensemble. The grant supported the PhD research of two students
