【 摘 要 】

The technique of accumulated photon echo is used in combination with a high-pressure diamond anvil cell to measure the splitting of the 4A2 ground state and the one-phonon spontaneous decay rate of the 2ABAR(2E) level at 10 K in ruby up to 4.3 GPa of hydrostatic pressure. The 4A2 ground-state splitting is found to be 0.383 +/- 0.001 cm-1 at ambient pressure, and increases with a slope of +(6 +/- 1) x 10(-3) cm-1/GPa. The spontaneous decay rate of 2ABAR(2E) increases only weakly with pressure. The pressure dependences of both quantities are accounted for in terms of the trigonal-field and spin-orbit-coupling parameters.
