In this seminar, I will present my research activities focused on nuclear structure studies using direct reactions. I will begin with my work on the pygmy dipole resonance (PDR), an excitation mode characteristic of neutron-rich nuclei, typically located near the neutron separation energy threshold. This topic is in the continuation of the work carried out during my PhD.

I will then turn to my postdoctoral research at the IGFAE laboratory in Santiago de Compostela, which is dedicated to investigating the structure of light nuclei in inverse kinematics using active targets. I will present several projects in which I am currently involved. First, I will discuss the analysis of data from an experiment conducted last summer at TRIUMF during the ACTAR campaign. This experiment, primarily devoted to the spectroscopy of ¹²Li via the ¹¹Li(d,p) transfer reaction, also provides an opportunity to study the PDR in ¹¹Li, which until now has only been measured using solid targets. I will present preliminary results on the angular distribution of inelastic scattering associated with this PDR state.

Next, I will focus on my main ongoing data analysis from an experiment carried out last January at RCNP in Osaka during the ATTPC campaign. The primary goal of this experiment was to study the spectroscopy of ¹⁸C via the ¹⁷C(d,p) transfer reaction. During the seminar, I will present the first preliminary results of a systematic study of the elastic scattering angular distributions for the different components of the beam. 

Finally, I will briefly introduce instrumentation work related to the development of gaseous detectors. The aim of this project is to evaluate the performance of the SRS electronics, developed by the RD51 collaboration at CERN, when coupled with active targets. To this end, we are constructing a small active target to test the SRS system and compare its characteristics with those of the GET electronics, which are currently used in active target systems such as ACTAR.
