Resumen:
Breakup reactions induced by a 30 MeV 7Li beam on a 144Sm target were measured
through the coincident detection of the light particles emitted in the reaction plane. The emphasis
of the measurements and data analysis was placed in the complete characterization of the reaction
by means of the identification of the breakup products and the experimental extraction of the
physically relevant magnitudes. The coincident yield of the emitted light particles was compared
with the results of kinematical calculations that were done assuming different distributions for
these magnitudes and taking into account the geometric response of the detection system. The
results of this comparison indicate in all cases a clear dominance of a process compatible with
the breakup of 6Li through the 3+ resonant state at 2.186 MeV following one-neutron transfer
from the projectile to the target, over the breakup of the projectile itself. Relative cross sections
as a function of the emission angle of the 6Li and the in-plane anisotropy of the subsequent
emission of breakup products were extracted from the data.
