Abstract :
104 magnesium atoms have been trapped in an optical lattice at the predicted magic wavelength of 469 nm. The trap depth of the lattice sites is 16 Er corresponding to a Lamb-Dicke parameter of η = 0.51. The temperature of atoms in the lattice is 10 μK. We performed magnetic field-induced spectroscopy on the strongly spin-forbidden clock transition and observed for the first time a 50 kHz broad carrier signal together with a 80 kHz broad red sideband.
