Dissociation of relativistic 10^{10}C nuclei in nuclear track emulsion

Dissociation of 1.2 A GeV $^{10}$C nuclei in nuclear track emulsionis is studied. It is shown that most precise angular measurements provided by this technique play a crucial role in the restoration of the excitation spectrum of the 2$\alpha$+2p system. Strong contribution of the cascade process $^{10}$C$\rightarrow ^9$B$\rightarrow ^8$Be identified.Comment: 5 pages, 3 figures, conference: The 21st European Conference on Few-Body Problems in Physics, Salamanca, Spain, 29th August - 3rd September, 201
