Abstract: Since the observation of a remarkable cosmic ray induced event, in experiments with emulsion chambers, a search for similar events was started. In spite of no observation of events showing the unusual aspect of Centauro I, another remarkable event with a high content of hadrons was observed. Moreover, this Centauro V has a hadron that interacts twice at deeper layers of the detector and has energy between (16-20)% of the total energy of the main interaction, the former figure for all showers and the last only for hadron-induced showers. Therefore, to classify it as a Centauro type event it is crucial to look for reasonable criterion to identify hadronic particles. Previous analysis adopted only one criterion for each shower observed in the films. Nowadays, an improved re-analysis uses at least two criteria for each shower. The main purpose of this paper is to show that the showers observed are properly identified as of hadronic origin and so we conclude that is an authentic Centauro event produced by the interaction of a hadron 500 m above the detector and interacting twice in the lower part of the chamber.
