| Abstract: |
The article focuses on experimental studies of carbon fusion reactions, specifically the fusion of two carbon-12 nuclei (12C+12C), which play a critical role in nucleosynthesis within massive stars. It details the challenges in measuring the fusion cross-section at astrophysically relevant low energies due to quantum effects and resonance structures, and describes advanced detection techniques combining γ-ray and charged-particle coincidence measurements. The STELlar LAboratory (STELLA) apparatus, installed at the low-background Felsenkeller underground laboratory in Dresden, Germany, employs rotating carbon targets, silicon detectors, and fast-timing LaBr3(Ce) scintillators to achieve high sensitivity and background suppression, enabling cross-section measurements below the nanobarn level. These precise measurements aim to improve understanding of stellar carbon burning processes and refine theoretical fusion models. [Extracted from the article] |
