Anomalous carbon nuclei

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

Results are presented from a bubble chamber experiment to search for anomalous mean free path (MFP) phenomena for secondary multicharged fragments (Z f =5 and 6) of a12C beam at 4.2 GeV/c per nucleon. A total of 50,000 primary interactions of carbon with propane (C3H8) were treated. Approximately 6,000 beam fragments with charges Z f =5 and 6 were analyzed in detail to search for an anomalous decrease of MFP. The anomaly is observed only for secondary carbon nuclei.

The experiment has been performed at the Laboratory of High Energies, JINR.
