What is claimed as new and desired to be secured by Letters Patent of the United States is:
1. A method of releasing a good yield of free barium atoms and barium ions in a gaseous medium comprising the steps of:
- dissolving a barium salt selected from the group consisting of BaCl2, Ba(NO3)2 and a mixture of BaCl2 and Ba(NO3)2 in a liquid fuel selected from the group consisting of hydrazine and liquid ammonia,
- providing a liquid oxidizer selected from the group consisting of OF2, F2 and ClF2 for the fuel,
- releasing the liquid fuel containing the barium salt simultaneously with releasing the liquid oxidizer so that the two released liquids contact each other whereby a hypergolic reaction takes place to release a high yield of luminous barium atoms and barium ions in the resulting flame.
