“…By gating on the specific Q-value peak, the mass combination of the reaction channel can be selected [19,20,24]. The Q-value analysis also demonstrated the negligible contribution from the F content of the target material to the present measurement, which was also verified by the EP-plot analysis [21,27].…”

“…Using the information of the detected recoil particle H and decay particle α (or p), together with the beam information, the momentum and energy of the remaining decay fragment O (or F) can be deduced according to the momentum conservation law [20,25]. The reaction energy, namely the Q value, can then be calculated by subtracting the beam energy from the total kinematic energy of the final three particles [19][20][21][22][23]26]:…”

The 6Li(16O,19Ne*)3H multi-nucleon transfer-reaction experiment was performed to populate the highly excited states in 19Ne. The subsequent decay particles, 4He or proton from the 19Ne resonant states, were detected in coincidence with the recoil 3H. The excitation-energy spectra of 19Ne were reconstructed by using the detected proton or 4He and the deduced 18F or 15O, respectively. The broad resonance at about 7.85 MeV (1/2+) was observed with partial decay widths updating the previously reported values, which may have significant impact on the destruction of 18F in astrophysical processes. Several resonances up to very high excitation energies have been identified with large α-clustering strength, which confirm the formation of the cluster structure with one-hole configuration in light nuclei, and encourage further systematic studies of cluster structure in 19Ne.

Measurements of the 2 H( 16 C, 16 C * → 4 He+ 12 Be or 6 He+ 10 Be) 2 H inelastic excitation and clusterdecay reactions have been carried out at a beam energy of about 23.5 MeV/u. A specially designed detection system, including one multi-layer silicon-strip telescope at around zero degrees, has allowed the high-efficiency three-fold coincident detection and therefore the event-by-event determination of the energy of the unstable nucleus beam. The decay paths from the 16 C resonances to various states of the final 10 Be or 12 Be nucleus are recognized thanks to the well-resolved Q-value spectra. The reconstructed resonances at 16.5(1), 17.3(2), 19.4(1) and 21.6(2) MeV are assigned as the 0 + , 2 + , 4 + and 6 + members, respectively, of the positive-parity (3/2 − π ) 2 (1/2 − σ ) 2 -bond linear-chain molecular band in 16 C, based on the angular correlation analysis for the 16.5 MeV state and the excellent agreement of decay patterns between the measurements and theoretical predictions. Moreover, another intriguing high-lying state was observed at 27.2(1) MeV which decays almost exclusively to the ∼6 MeV states of 10 Be, in line with the newly predicted pure σ-bond linear-chain configuration.

“…Over the past two decades, the coincident measurement of decay fragments has allowed the selection and reconstruction of resonant states that possess relatively large cluster probabilities, therefore avoiding the high level density of single-particle-type states [5,6]. To date, considerable theoretical and experimental research has been devoted to the study of cluster configurations in neutron-rich beryllium, carbon, and oxygen isotopes [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22].…”

α-cluster decay from ²⁴Mg resonances produced in the ¹²C(¹⁶O,²⁴Mg)α reaction*

An α-transfer and cluster-decay experiment, 12C(16O,24Mg→α+20Ne)α, was performed at a beam energy of 96 MeV. Both the recoil and the decay α particles were detected in coincidence, allowing to deduce the energy-momentum of 20Ne fragment. A number of resonant states of 24Mg are reconstructed up to an excitation energy of about 30 MeV. Owing to the experimentally achieved excellent resolutions on Q-value and excitation-energy spectra, the relative decay widths for each resonant state in 24Mg to various final states of 20Ne have been extracted, together with the total decay width. The obtained results provide a good test ground for theoretical descriptions of the multiple clustering configurations in 24Mg.
