Results of an investigation of collisional deexcitation of the metastable 6s6p&hthinsp;{sup 3}P{sub 0} state in atomic ytterbium by helium and neon buffer gases are reported. We find upper limits for the quenching cross sections to be {sigma}{sub He}{lt}13{times}10{sup {minus}22}&hthinsp;cm{sup 2} and {sigma}{sub Ne}{lt}8{times}10{sup {minus}22}&hthinsp;cm{sup 2}. The small cross sections may allow an ytterbium parity nonconservation experiment to be performed in a vapor cell. We have also measured the pressure broadening and shift of the 6s6p&hthinsp;{sup 3}P{sub 0}{r_arrow}6s7s&hthinsp;{sup 3}S{sub 1} and 6s{sup 2}&hthinsp;{sup 1}S{sub 0}{r_arrow}6s6p&hthinsp;{sup 3}P{sub 1} transitions by helium and neon. {copyright} {ital 1999} {ital The American Physical Society}
