why is deuterium-tritium reaction the most promising nuclear fusion reaction for future energy production?
lubasha [3.4K]

Answer:

The deuterium-tritium (DT, Figure 2) reaction is the most useful for fusion energy because it most easily overcomes the Coulomb repulsion, and it has the highest energy release among laboratory-feasible reactions.

Explanation:

When a deuterium nucleus (2H) and a tritium nucleus (3H) combine, the result is a helium nucleus and a very energetic neutron. Under the right circumstances, the energy released is sufficient to induce further fusion reactions.

Ultraviolet photoelectron spectroscopy (UPS) is an important analytical tool used to characterize the composition of materials i
Setler [38]

Answer:

The equation for the Kinetic Energy, KE_e, of the photo-emitted electrons is given as follows;

KE_e = h\cdot f- BE

Please find attached the required plot of the kinetic energy versus the frequency

Explanation:

The equation for the Kinetic Energy, KE_e, of the photo-emitted electrons is given as follows;

KE_e = h\cdot f- BE

Where:

h = Planck's constant = 6.63×10⁻³⁴ J·s

f = Frequency

BE = Binding Energy = 2.71 eV  for Calcium metal

f₀ = Threshold frequency for the material

The ionization energy is the energy required to free an electron from an isolated atom
