have been invistigated under 0-80kbar at room temperature using a diamond anvil high pressure microspeetroscopic system.According to crystal field theory
the crystal parameter formulars of energy levels of Eu

(in approximatary D2d point group symmetary site)are determind and fit with the experimental data of energy levels under high pressure.Then the ratios of crystal parameter variation
