Abstract

This paper presents multiplicity measurements that have been performed with ALICE based on minimum-bias data at 0.9 and 2.36 TeV. Results are shown of the pseudorapidity density and the multiplicity distribution in different phase space windows. The analysis and correction procedures are discussed and the results are compared to previous measurements and to model predictions.
