NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. The absolute cross sections for the reactions Li[superscript 7][...] and Li[superscript 7][...], have been measured in the range of energies and angles, [...], [...], using thin Li[superscript 7]-bearing targets. Solid state detectors were used to detect the scattered [alpha] particles. Nineteen scattering anomalies have been observed in this energy range. In the excitation energy range, 9.88 [...] MeV, six levels were observed. The measured cross sections were fitted in this energy region using a multilevel R-matrix theory model-program for the 7094 computer. The best fits were obtained with the assignments: 9.88(3/2[superscript +]), 10.26(3/2[superscript -]), 10.32(5/2[superscript 2-]), 10.60(7/2[superscript +]), 11.0(5/2[superscript 1]), 11.27(7/2[superscript +], 9/2 [superscript +]). Some alternatives for these assignments are discussed. The results were found to be consistent with the level structure of the analogue nucleus C[superscript 11]. The applications of the rotator model of the nucleus to the excited states of B[superscript 11] and c[superscript 11] are discussed.
