← ScienceWhich consequence results when exceeding the Gamow window, limiting energies required for stellar hydrogen fusion?
A)Increased radiation shielding effectiveness
B)Suppressed electron degeneracy pressure
C)Reduced reaction cross-section prevails
D)Runaway fusion reaction initiates✓
💡 Explanation
A lower energy threshold must prevail using quantum tunneling. Higher energies surpass coulomb barrier forces enabling runaway fusion because fusion probability increases exponentially with energy; therefore, a runaway reaction occurs rather than self-regulation at lower fusion rates.
