Optical clock based on two-photon spectroscopy of the nuclear transition in ion ${}^{229}$Th in a monochromatic field

V. I. Yudin, A. V. Taichenachev, O. N. Prudnikov +4

For the isotope ${}^{229}$Th we investigate the possibility of two-photon laser spectroscopy of the nuclear clock transition (148.38 nm) using intense monochromatic laser field at tw…
