Element Synthesis by Neutron Capture

Element Synthesis by Neutron Capture r-process

Element Synthesis by Neutron Capture s-process

Evidence Supporting the Stellar Hypothesis The pressures and temperatures of the cores of very large stars are adequate to permit not only hydrogen to burn but also helium and even heavier elements Explosions of large stars have been observed

Evidence Supporting the Stellar Hypothesis 3. Element technetium (Tc) 4. Relative abundances of the elements
