内容記述 | A diagnostic scheme for the measurement of the O^- density in afterglow plasmas is proposed and demonstrated. The present method is based on the fact that excited oxygen atoms (O^*) are produced by mutual neutralization between positive and negative ions (O^+O^-→O^*1+O). The absolute value of the emission coefficient ε_n due to O^*→O+hν is determined by visible emission spectroscopy with a calibrated detection system. The O^+ density n_O^+ is measured by a Langmuir probe combined with mass spectrometry. With the rate coefficient for the above reaction k_n , the O^- density can be evaluated as n_{O^-}=ε_n /(k_nn_{O^+}). In the present letter, the rate coefficient k_n has been determined experimentally from n_{O^-} measured by probe-assisted laser photodetachment. | |||||
