  • Question 1
    1 / -0

    The rest mass of a deuteron is equivalent to an energy of $$1876$$ MeV, that of a proton to $$939$$ MeV, and that of a neutron to $$940$$ MeV. A deuteron may disintegrate to a proton and a neutron if it

  • Question 2
    1 / -0

    A helium atom, a hydrogen atom and a neutron have masses of $$4.003 u$$, $$1.008 u$$ and $$1.009 u$$ (unified atomic mass units), respectively. Assuming that hydrogen atoms and neutrons can fuse to form helium, what is the binding energy of a helium nucleus?

  • Question 3
    1 / -0

    Assuming that about 20 MeV of energy is released per fusion reaction $$_1H^2+_1H^2\rightarrow _2He^4+E+$$ other particles, then the mass of $$_1H^2$$ consumed per day in a fusion reactor of power 1 megawatt will approximately be

  • Question 4
    1 / -0

    If mass of $$U^{235}=235.12142amu$$, mass of $$U^{236}=236.1205 amu$$, and mass of neutron $$1.008665 amu$$, then the energy required to remove one neutron from the nucleus of $$U^{236}$$ is nearly about

  • Question 5
    1 / -0

    In the nuclear reaction given by $$_2He^4+_7N^{14}\rightarrow _1H^1+X$$ the nucleus X is

  • Question 6
    1 / -0

    The binding energies per nucleon of deutreron $$(_1H^2)$$ and helium $$(_2He^4)$$ atoms are $$1.1 MeV$$ and $$7 MeV$$. If two deuteron atoms react to form a single helium atom, then the energy released is

  • Question 7
    1 / -0

    What would be the energy required to dissociate completely $$1 g$$ of $$Ca^{40}$$ into its constituent particles?
    Given: Mass of proton $$=1.007277 amu$$,
               Mass of neutron $$=1.00866 amu$$,
               Mass of $$Ca-40=39.97545 amu$$
               (Take $$1 amu=931 MeV)$$

  • Question 8
    1 / -0

    Calculate the binding energy of a deuteron atom, which consists of a proton and a neutron, given that the atomic mass of the deuteron is 2.014102 u 

  • Question 9
    1 / -0

    A stationary thorium nucleus $$(A=220, Z=90)$$ emits an alpha particle with kinetic energy $$E_{\alpha}$$. What is the kinetic energy of the recoiling nucleus?

    Directions For Questions

    The compound unstable nucleus $$_{92}^{236}U$$ often decays in accordance with the following reaction:
    $$_{92}^{236}U\rightarrow _{54}^{140}Xe+_{38}^{94}Sr+$$ other particles
    During the reaction, the Uranium nucleus "fissions" (splits) into the two smaller nucleii. The reaction is energetically favorable because the smaller nucleii have higher nuclear binding energy per nucleon (although the lighter nuclei have lower total nuclear binding energies, because they contain fewer nucleons).
    Inside a nucleus, the nucleons (protons and neutrons) attract each other with a "strong nuclear" force. All nucleons exert approximately the same strong nuclear force on each other. This force holds the nucleus together. Importantly, the strong nuclear force becomes important only when the protons and neutrons are very close together at intranuclear distances.
