Question

1. Find the speeds of alpha particles with energies of 1 MeV? 2. Calculate the kinetic energy in ergs and MeV, and the value of Hr for alpha - particles moving at each of the following speeds (in cm/sec): 1 × 10^8, 5 × 10^8, 7.5 × 10^8, 1 × 10^9, 1.25 × 10^9, 1.5 × 10^9, 1.75 × 10^9, 2 × 10^9, 2.5 × 10^9, 3 × 10^9, 5 × 10^9, 1 × 10^{10} and 2 × 10^{10} 3. The nuclide Rn^211 emits three groups of alpha particles, with kinetic energies of 5.847 MeV, 5.779 MeV, and 5.613 MeV, respectively. Associated with the alpha particles are ? - rays with energies of 0.0687 MeV, 0.169 MeV, and 0.238 MeV. Construct a decay scheme based on these data. 4. The nuclide U^233 emits six groups of alpha particles, with kinetic energies of 4.816 MeV, 4.773 MeV, 4.717 MeV, 4.655 MeV, 4.582 MeV, and 4.489 MeV, respectively. Gamma - rays with energies of 0.0428 MeV, 0.0561 MeV, and 0.099 MeV have also been reported. Construct a decay scheme based on these data.
