What process is the main mechanism for converting helium nuclei into carbon nuclei?

Answer

Triple-Alpha Process

The Triple-Alpha Process is the main mechanism for helium conversion, requiring the fusion of three helium nuclei ($ ext{}^4 ext{He}$) together to form a single carbon nucleus ($ ext{}^{12} ext{C}$), usually proceeding via unstable beryllium-8.
