“…Resonance states above E ex = 9 MeV have been studied via 10 B(p, α) and other reactions such as 12 C(p, d) 11 C [8][9][10][11][12][13][14][15][16][17]. The resonances typically have widths of the order of 100 keV, but their α-decay widths Γ α are not known with a good precision, and even the spin and parity (J π ) have not been clearly determined yet for some of the states.…”

α-resonance structure in11C studied via resonant scattering of7Be+α

Background: The resonance structure in 11 C is particularly of interest with regard to the astrophysical 7 Be(α, γ) reaction, relevant at high temperature, and to the α-cluster structure in 11 C.Purpose: The measurement was to determine unknown resonance parameters for the high excited states of 11 C. In particular, the α decay width can be useful information to discuss α cluster structure in 11 C.Methods: New measurements of the 7 Be+α resonant scattering and the 7 Be(α, p) 10 B reaction in inverse kinematics were performed for center-of-mass energy up to 5.5 MeV, and the resonances at excitation energies of 8.9-12.7 MeV in the compound 11 C nucleus were studied. Inelastic scattering of 7 Be+α and the 7 Be(α, p1) 10 B * reaction were also studied with a simultaneous γ-ray measurement. The measurements were performed at the low-energy RI beam facility CRIB (CNS Radioactive Ion Beam separator) of the Center for Nuclear Study (CNS), the University of Tokyo. Results:We obtained excitation functions of 7 Be(α, α0) 7 Be (elastic scattering), 7 Be(α, α1) 7 Be * (inelastic scattering), 7 Be(α, p0) 10 B, and 7 Be(α, p1) 10 B * . Many resonances including a new one were observed and their parameters were determined by an R-matrix analysis. Conclusions:The resonances we observed possibly enhance the 7 Be(α, γ) reaction rate but in a smaller magnitude than the lower-lying resonances. A new negative-parity cluster band, similar to the one previously suggested in the mirror nucleus 11 B, is proposed.

“…The signals from the PMTs were used to monitor the beam, to obtain a "start" signal for time of flight (TOF) measurements, and to identify the main beam contamination, 7 Be, which has the same q/m as 14 O and could not be separated by the velocity filter of MARS. Because the Coulomb barrier is smaller for 7 Be + α than for 14 O + α, the cross section of the reaction 7 Be(α, p) 10 B [9] at low energies could be up to 10 3 times larger than that for the 14 O(α, p) 17 F reaction. Amplitude analysis of the PMT signals reduced the 7 Be/ 14 O ratio to the 10 −4 level.…”

Single and double proton emissions from theO14+He4interaction

We observed single and double proton emissions in the 14 O + 4 He interaction by the thick target inverse kinematic (TTIK) method at initial energy for 14 O at 32.7 MeV. We found that the protons mainly originate from the resonance excitation of states in 18 Ne. The observed states in 18 Ne decay by protons mainly to proton unstable states in 17 F. It was found that the decay of a state in 18 Ne at E ex = 8.45 MeV demonstrates the features of a decay by a correlated proton pair. The observed properties of the 14 O + 4 He interaction make a previous interpretation for the rate of 14 O( 4 He, p) 17 F at astrophysical energies suspect. We show how the TTIK method should be modified to obtain the data of astrophysical interest.
