The 11B(p,aa)4He reaction was measured
at eight incident proton energies, from 2 to 5.5 MeV, for the collinearity configurations
(an a-particle at rest in the c.m. system). The results are
compared with predictions of the Schäfer model. Involvement of the 12C states
with excitation energy between 17.8 and 21 MeV is discussed.
