Tendon injuries occur commonly in horses and their repair through scar tissue formation predisposes horses to a high rate of re-injury. Pluripotent stem cells may provide a cell replacement therapy to improve tendon tissue regeneration and lower the

We report on the development of a trapped-ion, microwave frequency standard based on the 12.6 GHz hyperfine transition in laser-cooled ytterbium-171 ions. The entire system fits into a 6U 19-inch rack unit ($51\times49\times28$ cm) and comprises lase

An electron‐beam ion trap (EBIT) has just been completed in the Clarendon Laboratory, Oxford. The design is similar to the devices installed at the Lawrence Livermore National Laboratory. It is intended that the Oxford EBIT will be used for x‐ray

The authors report the observation of the 1S-2S two-photon transition in atomic hydrogen in an atomic beam, excited by light from a narrow-band continuous-wave laser. The excitation takes place in a collision-free environment and detection of the res

Optical pumping experiments at 377 nm on the resonance transition of atomic thallium (6p1/2–7s1/2) are reported. The potential of this technique in the search for an electric dipole moment which arises through PT-violation is assessed. Linewidths o

The two-photon transitions 4S1/2→6S1/2 and 4S1/2→4D5/2 in atomic potassium have been observed free of the first-order Doppler effect. The rate for the S-D transition, which has been detected for the first time, is two orders of magnitude lower th
