Efficient Quenching of Population Trapping in Excited Yb superscript +

The efficiency of various buffer gases in quenching the population trapping states of laser excited ytterbium ions is described. Highly efficient in quenching the population of the trapping states, N subscript 2 has been identified as the most suitable buffer gas to use with ytterbium for the development i=of a trapped ion microwave frequency standard.
