Synopsis Fragmentation dynamics of two isomers of C 3 H 4 , propyne (CH 3 CCH) and allene (CH 2 CCH 2 ), is in-vestigated by 50 keV/u Ne 8+ impact. Isomerization processes are identified in two-body fragmentation channels of C 3 H 4 2+ for both isomers. Besides, we observe two new dissociation channels of C 3 H 4 3+ trications, H + + C 3 H 3 2+ and H 2 + + C 3 H 2 2+ . For CH 2 CCH 2 3+ , the peak and shoulder structures in the kinetic energy release spectrum of H + + C 3 H 3 2+ channel are attributed to different geometries of the C 3 H 3 2+ products by comparing with theoretical cal-culation.
