Alkali age

Soon after the first experiments on halogen molecules, it became clear that alkali collisions with many other, electronegative and even electropositive, molecules lead to ionization. Many of these results have been published now, especially on relatively small inorganic molecules, whereas experiments on large organic molecules have been announced. Moreover the history of the chemical reaction beam research seems to repeat itself after an alkali-age of about five years the first non-alkali experiments have been reported, which will be discussed in the next section.
