Abstract
A baroreceptor analysis system has been assembled to measure {alpha}-{alpha} spectra in coincidence (resolution 2 {tau} = 10 ns). The correlations in energy and angle of the {alpha}-particles emitted from the reaction {sup 11}B(p,{alpha}) have been studied using 163 keV protons produced by a Van-de-Graaff accelerator. Evidence has been obtained for the sequential decay of {sup 12}C{sup *} (16.11 MeV) via the 0{sup +} and 2{sup +} states of {sup 8}Be. Contributions from the {sup 8}Be{sup *}(4{sup +}) level or from the simultaneous break-up of {sup 12}C{sup *} (16.11 MeV) into three {alpha}-particles cannot be excluded. (author) [French] On a mis au point un dispositif d'analyse biparametrique de spectres {alpha}-{alpha} en coincidences (resolution 2 {tau} = 10 ns).
