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

TL;DR

This study investigates the dissociation of relativistic $^{10}$C nuclei in nuclear track emulsion, revealing detailed excitation spectra and cascade processes, enhancing understanding of nuclear fragmentation at high energies.

Contribution

It introduces precise angular measurement techniques in nuclear track emulsion to reconstruct excitation spectra and identify cascade decay processes of $^{10}$C nuclei.

Findings

Identification of cascade decay $^{10}$C$ ightarrow ^9$B$ ightarrow ^8$Be.

Restoration of excitation spectrum of 2$ ext{α}$+2p system.

Demonstration of the importance of angular measurements in nuclear dissociation studies.

Abstract

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.
