Description
Multi $\alpha$ clustering structure in nuclei is an attractive topic in nuclear physics, especially the $\alpha$ condensates. An experiment for $^{12}$C($^{16}$O,$^{20}$Ne*) $^8$Be multi-nucleon transfer reaction and cluster-decay was performed at China Institute of Atomic Energy(CIAE) at a beam energy of 6 MeV/u in 2021. A specially designed telescope system played an essential role to measure the breakup alpha particles of $^{20}$Ne and the correlated recoil nuclei $^8$Be(2$\alpha$). This work aims to find the multi $\alpha$ clustering structure and the condensed states in $^{20}$Ne. The reaction Q-value spectra and the excitation spectra were deduced and reconstructed by the detected $\alpha$ particles and the beam energy. We have found several multi $\alpha$ coincidence events in present data analysis, especially triple and quadruple coincidence events, and we are trying to use these events to explore the novel multi $\alpha$ states in $^{20}$Ne.
