In this contribution, an analysis of an experiment with the 30 and 52 MeV 7Li beam and the 7LiF and 6LiF targets is given, emphasizing population of cluster states by triton transfer to 7Li. Results concerning both reactions are given and discussed. Aside from the dominant α + d structure in 6Li, a rather large overlap with 3He+t cluster configuration populates cluster states in 10Be by triton pick-up. A comparision with t pick-up from 7Li, resulting with detected α instead of 3He, with a considerably higher Q-value is given. A special attention was paid to analysing and compensating non-uniformity of thicknes of standard 50 μm thin silicon detectors used in the measurement. Rather than measuring their thickness independantly, a method was derived to calculate and compensate the thickness variation directly from the measured data.
