Abstract The11B(p, 3α) reaction has been investigated in the energy range fromE c.m.=22 to 1100 keV with the use of either a proton beam and a11B solid target or with the use of a11B heavy ion beam incident on a hydrogen jet gas target. The reaction mechanisms have been studied via kinematically complete coincidence measurements showing that the reaction proceeds predominantly by a sequential decay via8Be. The measurement of absolute cross sections,α-angular distributions and excitation functions is reported. The astrophysicalS(E) factor has been described by means of an empirical fit to the data, leading to a zero-energy intercept ofS(0)=197±12 MeVb. Conclusions drawn on the use of this reaction as an advanced fuel in fusion reactors remain essentially unchanged by the present data.
