    Beschreibung / Inhaltsverzeichnis: Riassunto Abbiamo in precedenza studiato il processo di collisione di energy pooling in una miscela di sodio e potassio. In questo lavoro si analizzano i particolari effetti indotti dalla presenza di alcuni Torr di gas tampone introdotti nella cella. Viene dimostrato che il gas tampone favorisce il processo di trasferimento di energia fra Na(3P) e K(4S), che viene rivelato attraverso gli effetti indotti sugli stati altamente eccitati popolati dalle collisioni Na(3P)/Na(3P) e K(4P)/K(4P).
    Kurzfassung: Резюме Ранее авторы в амальгаме натрия и калия исследовали распределение энергии в смесях щелочных паров. В этой статье мы описываем особенности, возникающие при введении буферного газа в ячейку. Мы поквзываем, что буферный газ усиливает обмен энергией между Na(3P) и K(4S), который детектируется через эффекты, связанные с высоко возбужденными состояниями, заселенными при Na(3P)/Na(3P) и K(4P)/K(4P) соударенияш.
    Notizen: Summary Energy pooling in alkali vapour mixtures has been previously investigated by us in an amalgam of sodium and potassium. In this paper we describe the peculiar features appearing when some buffer gas is introduced in the cell. We demonstrate that the buffer gas enhances the energy transfer between Na(3P) and K(4S), which is detected through the effects induced on the highly excited states populated by the Na(3P)/Na(3P) and K(4P)/K(4P) collisions.

    Notizen: Summary Diode laser spectroscopy of ammonia ro-vibrational overtone transitions has been performed in the near IR, by using direct absorption, wavelength modulation, and two-tone frequency modulation techniques. Pressure broadening coefficients in air, hydrogen, helium and self-broadening have been measured. The high sensitivity of the apparatus permitted the detection of 70 p.p.m. of NH3 in air per meter of path at atmospheric pressure. New lines have been observed in the 719.9 nm band.

    Notizen: Summary Diode laser spectroscopy of water vapour has been performed in the near IR and the pressure broadening coefficients in nitrogen and in air have been measured for one rotovibrational line. Detection of water vapour in the atmosphere has been obtained and an evaluation of the sensitivity of our apparatus is reported. Discussion for further improvements is made.
