Abstract : Experimental data on heavy particle collisions of relevance to atomic weapons debris motion are critically reviewed with emphasis on electron capture-and-loss cross-section measurements and possible systematic errors attending the experiments. Discrepancies of the order of 50 percent can be understood on the basis of differences in experiments. Four phenomenological theories (Rapp and Francis, Firsov, Firsov-Russek, and Classical Binary Encounter) are summarized and critically evaluated for applicability to heavy particle collisions. The predictions of these theories are compared with experimental data. A theorem pertinent to energy distributions in electron-ion collision experiments is presented. The report concludes with recommendations on future informational needs. (Author)
