States in 10Be populated in 6,7Li( 7Li,3,4He)10Be* reactions at 30 and 52 MeV
Get PDFIn 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
CLUSTERING IN 11,12,13C∗
No full textCharacterization of the excited states of 11C, 12C, 13C isotopes was performed using experimental data collected at the INFN-LNL in Italy. The study employed a 95 MeV 14N beam on 10B targets to probe clustering phenomena in carbon isotopes. The experimental setup included a detector system covering polar angles from 15◦ to 72◦, enabling the study of reactions with two and three products in the exit channel. Analysis of the three-product exit channels is presented to provide insight into the process of analyzing such reactions. Presented results for the 7Be+4He, 8Be+4He, and 9Be + 4He decays of 11C, 12C, 13C, respectively, unveil states at 7.6, 9.7, and 14.1 MeV in 12C, 8.1 and 8.4 MeV in 11C, as well as a broad peak centered at 13.6 MeV with a possible contribution of states from 13.4 to 14.1 MeV in 13C. The detection of these states serves as a crucial validation of the analysis and data selection procedures, representing an initial step before exploring other exit channels
The 19F(α, p)22Ne Reaction at Energies of Astrophysical Relevance by Means of the Trojan Horse Method and Its Implications in AGB Stars
No full textThe main source of F-19 in the universe has not yet been clearly identified and this issue represents one of the unanswered questions of stellar modeling. This lack of knowledge can be due to the F-19(alpha, p)Ne-22 reaction cross-section that has proven to be difficult at low energies: direct measurements stop only at about similar to 660 keV, leaving roughly half of the astrophysical relevant energy region (from 200 keV to 1.1 MeV) explored only by R-matrix calculations. In this work, we applied the Trojan Horse Method to the quasi-free three-body Li-6(F-19, p(22)Ne)d reaction performed at E-beam = 6 MeV in order to indirectly study the F-19(alpha, p)Ne-22 reaction in the sub-Coulomb energy region. In this way, we obtained the cross-section and the reaction rate in the temperature region of interest for astrophysics and free from electron screening effects. A brief analysis of the impact of the new measured reaction rate in AGB star nucleosynthesis is also presented
Study of 24Mg resonances relevant to carbon burning nucleosynthesis
No full textWe have studied the decays of the resonances of 24Mg at excitation energies 1-6 MeV above the 12C+12C decay threshold, using the 12C(16O,α) 24Mg* reaction at E(16O) = 94 MeV. Some preliminary results are presented and further analysis is in progress

Study of interstrip gap effects and efficiency for full energy detection of Double Sided Silicon Strip Detectors
Get PDFIn this work is reported a study on the response of double sided silicon strip detectors.
In order to investigate the effect of the electrode segmentation on the detector response, two
experiments were performed aimed to measure the efficiency for full energy detection. Results
show that the efficiency for full energy detection, that is directly related to effective width of
the inter-strip region, varies with both detected ion energy and bias voltage. The experimental
results are qualitatively reproduced by a simpli ed model based on the Shockley-Ramo-Gunn
framework.Ciencias Integrada
