A particle of ionizing radiation creates 4,600 ion pairs in the gas inside a Geiger tube as it passes through. What minimum energy (in J) was deposited, if 21.0 eV is required to create each ion pair?
If all of this energy is converted to thermal energy in the gas, what is its temperature increase (in K), assuming 55.0 cm3 of ideal gas at 0.300 atm pressure? (The small answer is consistent with the fact that the energy is large on a quantum mechanical scale but small on a macroscopic scale. Assume the initial temperature of the gas is 293 K.)
Alpha particles of energy 8.4 MeV are incident on a silver foil of thickness 6.5 μm. For a certain value of theimpact parameter, the alpha particles lose exactly half their incident kinetic energy when they reach theirminimum separation from the nucleus. Find the minimum separation, the impact parameter, and the scatteringangle.
Estimate the approximately value of the temperature necessary to overcome the Coulomb repulsion barrier of the D-T fusion reaction and discuss why this very high temperature is needed?
