摘要
If matter is suddenly put under a high pressure, for example, a pressure of 100 Mb = 10(14) dyn/cm(2), it can undergo a transformation into molecular excited states, bound by inner electron shells, with keV potential wells for the electrons. If this happens, the electrons can under the emission of X-rays go into the groundstate of the molecule formed under the high pressure. At a pressure of the order similar to 10(14) dyn/cm(2), these molecules store in their excited states an energy with an energy density of the order similar to 10(14) erg/cm(3), about 1,000 times larger than for combustible chemicals under normal pressures. Furthermore, with the much larger optical path length of keV photons compared to the path length of eV photons, these superexplosives can reach at their surface an energy flux density (c = 3 x 10(10) cm/s) of the order (c/3) x 10(14) = 10(24) erg/cm(2)s = 10(17)W/cm(2), large enough for the ignition of thermonuclear reactions.
