To conduct such research a new experimental apparatus was established.With this setup the two-photon excitation spectra of Barium and one-photonexcitation spectra of Strontium Rydberg atoms were recorded and identified.The Stark spectra of Strontium atoms showed the "l-mixing" and "n-mixing"features. By changing laser wavelength and external electric field strengthsimultaneously, the scaled-energy spectra of Strontium 〓 Rydberg atomsat constant scaled-energy ε=-3.00,-2.50 and -1.88 were recorded for thefirst time. The experimental spectra were Fourier transformed and yielded therecurrence spectra.

Strontium isotope stratigraphy relies on the fundamental principle that the marine strontium is isotopically homogenous world-wide at any time and the 87Sr/86Sr ratio of strontium in seawater of geological history has varied through time. By means of the 87Sr/86Sr ratio of marine carbonate which should record the original composition of sea water, we can date the marine sediments, research global events, such as history of basin subside, sea level change, orogenic events and palaeoclimate variation.
