英文摘要
The electron-to-proton mass ratio is known as a dimensionless physical constant, which is about 1/1836. By the test of the stability of such dimensionless physical constants, we can test the Einstein equivalence principle. With the precision spectroscopy of the ultracold KRb molecules, we have succeeded in specifying the levels which are most suitable for the test of the stability of the electron-to-proton mass ratio, and succeeded in the precision spectroscopy of them. The statistical error of our measurement exceeds the accuracy of the experiments done by other groups so far.
