In an experiment performed at the ISOLDE facility of CERN, the super-allowed -decay branching ratio of C was determined with a high-precision single-crystal germanium detector. In order to evaluate the contribution of the pile-up of two 511 keV 
quanta to one of the -ray peaks of interest at 1021.7 keV, data were not only taken with C, but also with a 
Ne beam. The final result for the super-allowed decay branch is 1.4638(50)%, in agreement with the average from literature.
