Bloch-Bradbury mechanism

This process proceeds by the two-stage Bloch-Bradbury mechanism (Bloch Bradbury, 1935 Alexandrov, 1981) starting with the formation of a negative ion (rate coefficient att) in an unstable auto-ionization state (r is the time of collisionless detachment) ... 

The second stage of the Bloch-Bradbury mechanism includes collision with the third-body particle M (density no), leading to relaxation and stabilization of O2 or collisional decay of the unstable ion ... 

Because oxygen is probably the most extensively studied molecule in both experimental and theoretical investigations of low-energy electron attachment, the experimental results and detailed discussion are presented in this paper particularly for O2. The only accepted mechanism has been the overall two-step three-body mechanism, which was originally suggested by Bloch and Bradbury [79] (referred to below as BB ) and was later modified by Herzenberg [80] to make it consistent with modern experimental data. The BB mechanism for O2-M mixture, where M is a molecule other than O2, is expressed as follows ...
