DESCRIPTION:Speakers: Miguel Lozano-González (IGFAE-USC)\nProton and neut
 ron removal reactions across the Be-Li chain close to the drip line have b
 een investigated to establish the role of the Geometrical Mismatch Factor 
 (GMF) and the Short-Range Correlations (SRC) effects [1] in lowering the c
 ross sections\, as observed previously in He-Li nuclei when compared to th
 eoretical predictions [2] in what is widely known as the *quenching* of Sp
 ectroscopic Factors (SFs).\n\n\nThe experiment E748 was performed at GANIL
  using $^{10}\\text{Be}$ and $^{12}\\text{Be}$ beams at 30 AMeV impinging 
 on a $\\text{CD}_{2}$ target\, with an intensity of $3\\times 10^{5}$ and 
 $2\\times 10^{4}$ pps respectively. The light recoil's angle and energy we
 re detected using 8 MUST2 telescopes [3]\, and a zero-degree detector cons
 isting of an ionization chamber and a plastic scintillator that permitted 
 the identification of the heavy recoil.\n\nThe missing-mass technique was 
 used to reconstruct the excitation energy spectrum\, from which cross-sect
 ions have been extracted. Particular attention has been paid to the $^{10}
 \\text{Be}(\\text{d}\,^{3}\\text{He})^{9}\\text{Li}$ and $^{12}\\text{Be}(
 \\text{d}\,^{3}\\text{He})^{11}\\text{Li}$ transfer reactions\, but also t
 o the $^{10}\\text{Be}(\\text{d}\,\\text{t})^{9}\\text{Be}$ channel as it 
 enables further constraints to these two phenomena along the same isotopic
  chain. \n\nThis work will present preliminary results of the angular dist
 ributions for all the interesting channels\, alongside a study of the afor
 ementioned *quenching* factor ($R_{\\text{S}}$ in the literature) by compa
 ring experimental SFs to Shell Model calculations. The elastic channels wi
 ll also be displayed as a validation mechanism of the normalization factor
