A breakdown of the spin dependence of the electron reflection due to organic molecules or amorphous carbon deposited onto a metallic film has been observed in the past. The goal of the present work is to further elucidate the physics of this phenomenon by studying it in ways not yet studied in the past. The most intriguing observation of the present study is that the breakdown phenomenon appears in a relatively well defined electron energy range between 2 and about 200 eV kinetic energy. Outside this energy range the breakdown phenomenon is not observed. However, an explanation of the breakdown phenomenon is still missing.
