Doppler cooling and trapping on forbidden transitions
T. Binnewies, G. Wilpers, U. Sterr +5
Ultracold atoms at temperatures close to the recoil limit have been achieved by extending Doppler cooling to forbidden transitions. A cloud of ^40Ca atoms has been cooled and trapp…

Efficient magneto-optical trapping of a metastable helium gas
F. Pereira Dos Santos, F. Perales, J. Leonard +6
This article presents a new experiment aiming at BEC of metastable helium atoms. It describes the design of a high flux discharge source of atoms and a robust laser system using a…

Penning collisions of laser-cooled metastable helium atoms
F. Pereira Dos Santos, F. Perales, J. Leonard +6
We present experimental results on the two-body loss rates in a magneto-optical trap of metastable helium atoms. Absolute rates are measured in a systematic way for several laser d…
