Progress Report 3 on Decompositions Reactions of Laser-Initiated Explosives

摘要

In the third progress report, initial and delayed emission spectra of primary and secondary explosives, obtained after UV laser light irradiation as well as after Rb-laser light irradiation, are reported. The initial spectra of the primary explosives reveal continua emission with line inversion at the position of the metal atoms present in the explosive molecule. After a time delay of a few hundred nanoseconds, the continuum has disappeared and other decomposition products show up. The emission spectra are independent of the wavelength of the laser light used (193 nm, 248 nm and 693.4 nm). Secondary explosives do not show the two-step behavior. The decomposition products are present from the start. Some minor differences seem to be present, but this is not certain.
