Abstract :
Summary form only given. Atom guiding through hollow optical fibres has been achieved previously using dipole light forces. Both blue and red detuned laser frequencies have been employed to create repulsive and attractive forces for light introduced into the fibre and the hole respectively. In the experiments described here, we report the first guiding of excited state helium atoms through hollow optical fibres. We employ helium atoms in the metastable 2/sup 3/S/sub 1/ state.
