| Research Abstract |
I performed vacuum ultraviolet (VUV) absorption spectroscopy on high-pressure krypton (Kr). An absorption profile at around 124 nm was unambiguously separated into two spectral parts: one the atomic Kr absorption peak at 123.6 nm and the other the absorption centered at 125.0 nm caused by Kr dimers (Kr2) . The absorption caused by Kr dimers was proportional to the square of Kr pressure, which was in agreement with the theoretical behavior. I, therefore, have concluded that Kr dimers existed in high-pressure Kr even at room temperature. Then I tried to photo-excite Kr dimers to produce Kr excimers (Kr2*). Unfortunately no positive results were obtained.
