We study the hyperfine splitting of an electron in hydrogen-like 209 Bi 82+. It is found that the hfs energy splitting can be explained well by considering the g-factor reduction due to the binding effect of a bound electron. We determine for the first time the experimental value of the magnetic moment of a tightly bound electron.

To further improve the performance of Monte Carlo simulations of first-order phase transitions we propose to combine the multicanonical approach with multigrid techniques. We report tests of this proposition for the d-dimensional Φ4 field theory in two different situations. First, we study quantum tunneling for d = 1 in the continuum limit, and second, we investigate first-order phase transitio...
