In this work, two rather different experiments with their respective analysis have been described. The first experiment concerned the 20Ne(d,p)21 Ne transfer reaction and the second the 12 C+12C fusion reaction. An experiment of 20 Ne(d,p)21 Ne transfer reaction was performed in Munich, Germany using the Quadrupole Dipole Dipole Dipole (Q3D) magnetic spectrograph. This experiment has aimed at the investigation of spectroscopic information around the Gamow window of the 17O(α,γ)21 Ne located between Ex = 7.65-8.05 MeV. The stated experiment was performed using an 21Ne implanted target on carbon and covered the excitation energies varying from 6.9 MeV to 8.5 MeV. Sixteen states were identified, three of which, the 8.328(6) MeV, 6.977(17) MeV and 6.960(2) MeV have first been observed in this work. Within the Gamow window however, only one state, the 7.955(2) MeV by correspondence to the 7.9603(10) Mev as recorded in literature, has been identified. Out the sixteen states, this work made eleven firm assignments and two “tentative” assignments. The 12 C+12 C fusion reaction was performed at TRIUMF, Canada using TUDA, the TRIUMF UK Detector Array. The experiment covered the centre of mass located between 3.4 to 4.02 MeV. The aim of this work was the determination of the cross section, which would help, at theses energies, reduce uncertainties observed in present data sets. Analysis such ADCs and TDCs calibrations, different cuts selection necessary for particle identification are presented.
