\indent First results of the exposure of nuclear track emulsions in a
secondary beam enriched by 9C nuclei at energy of 1.2 A GeV are described.
The presented statistics corresponds to the most peripheral 9C interactions.
For the first time a dissociation 9C →33He not accompanied by target
fragments and mesons is identified.\parComment: 7 pages, 6 figures, 2 tables, Presented at Advanced Studies Institute
