Аннотация:Results of an experimental study of singlet oxygen formation in N2: O2 mixtures in a
non-self-sustained discharge plasma produced by an electron beam are examined. Two
mechanisms of singlet oxygen formation are identified. The first mechanism involves direct
excitation of oxygen molecules by plasma electrons; this mechanism is not related to the
level of vibrational excitation of nitrogen molecules or with the O2: N2 ratio. The second
mechanism is thought to be related to energy transfer (possible, indirect) from nitrogen to ...
