“…The corresponding Rmatrix results for the 14.582-MeV state [24] do not explicitly favor either I π = 7 2 + or 9 2 + , but the total width is 285 keV with α0 / tot = 0.86 and n0 / tot = 0.14, in very close agreement with the current results.…”

“…Freer et al [24] have performed an R-matrix analysis on states in this excitation energy region and conclude that the 13.76-MeV level has I π = 5 2 + and a width of 337 keV, significantly more than the 143 keV measured here. The partial branching ratios in Ref.…”

“…Finally, it is worth drawing attention to the fact that Freer et al [24], in their recent R-matrix analysis, note that the narrow widths required (due to the centrifugal barrier) and the interference when including I π = 9 2 − states below ≈16 MeV cause problems for the molecular-band interpretation of Ref. [7].…”

The 9 Be( 6 Li, d) 13 C * reaction at a beam energy of 42 MeV has been investigated using a large-acceptance silicon-strip detector array and the high-resolution Q3D magnetic spectrograph. The Q3D facilitated the unambiguous determination of the reaction channel via identification of the deuteron ejectile, thereby providing the spectrum of excited states in 13 C in the range from 10.7 to 15.0 MeV. The silicon array was used to detect and identify the 13 C recoil-breakup products with efficiencies of up to 49%. The results obtained for the absolute partial branching ratios represent the first complete measurements for states in this energy region and allow the extraction of reduced widths. The quantities measured for n0 / tot and n1 / tot are 0.91 ± 0.11 and 0.13 (10.753 MeV), 0.51 ± 0.04 and 0.51 ± 0.04 (10.818 MeV), 0.68 ± 0.03 and 0.42 ± 0.02 (10.996 MeV), 0.49 ± 0.08 and 0.71 ± 0.11 (11.848 MeV), and 0.49 ± 0.08 and 0.53 ± 0.08 (12.130 MeV), respectively. For the two observed higher-lying energy levels, α0 / tot and n1 / tot have been measured as 0.54 ± 0.02 and 0.45 ± 0.02 (13.760 MeV) and 0.94 ± 0.03 and 0.13 ± 0.02 (14.582 MeV), respectively. The consequences for the proposed molecular structures in 13 C are explored following the extraction of reduced widths.

“…The technique of thick target resonant scattering provides an extremely useful tool in the study of α-cluster states [1], and has been used in a number of experiments in recent years (see, for example, [2][3][4][5][6][7][8][9][10][11][12]). In this method the scattering chamber is de-coupled from the beam line using a thin window (typically Mylar s or Havar s ), and filled with He gas.…”

a b s t r a c tA Monte Carlo code has been developed to simulate resonant scattering reactions using the thick gas target technique in inverse kinematics. Results are presented for the 4 He( 20 Ne,α) 20 Ne reaction at 70 MeV, and compared to an experimental measurement which utilised an array of segmented silicon strip detectors. In the case studied, angular straggling in the chamber window is found to dominate the excitation energy resolution.
