| Outline of Final Research Achievements |
In order to understand shock induced initiation phenomena of explosives, pentaerythritol tetranitrate (PETN) single crystal compressed by nanosecond shockwave pulse induced by pulsed laser irradiation was investigated. Equation-of-state parameters of thin platelet PETN single crystal compressed along with [110] direction were measured. Measured shock wave velocity and particle velocity relation agrees well with literature data measured by conventional methods. Shock induced frequency shift of the peaks was observed by time-resolved Raman spectroscopy, and showed the different behavior depending on each vibrational mode. Pressure induced peak shift at 1293 cm-1 mode was clearly observed.
