- If two nuclei are to fuse in a nuclear reaction, they must be moving fast enough so that the repulsive Coulomb force between them does not prevent them for getting within R1014mof one another. At this distance or nearer, the attractive nuclear force can overcome the Coulomb force, and the nuclei are able to fuse. (a) Find a simple formula that can be used to estimate the minimum kinetic energy the nuclei must have if they are to fuse. To keep the calculation simple, assume the two nuclei are identical and moving toward one another with the same speed v. (b) Use this minimum kinetic energy to estimate the minimum temperature a gas of the nuclei must have before a significant number of them will undergo fusion. Calculate this minimum temperature first for hydrogen and then for helium. (Hint: For fusion to occur, the minimum kinetic energy when the nuclei are far apart must be equal to the Coulomb potential energy when they are a distance R apart.)arrow_forward(a) Calculate the radius of 58Ni, one of the most tightly bound stable nuclei. (b) What is the ratio of the radius of 58Ni to that at 258Ha, one of the largest nuclei ever made? Note that the radius of the largest nucleus is still much smaller than ?le size of an atom.arrow_forwardWhile Uranium-235 is commonly used in nuclear power plants, the isotope U-238 is more commonly found in nature. a) How many neutrons are in the nuclei of U-235? b) How many neutrons are in the nuclei of U-238? Given the mass of 1 proton is 1.007825 amu, 1 neutron is 1.008665 amu and the binding energy of 1 amu is 931.49 MeV(1.MeV=1x10^6 eV). c) If the mass of U-235 is 235.0439299 amu, what is the mass defect in amu? d) What is the binding energy in MeV?arrow_forward

Such a star could be thought of as a giant atomic nucleus. If a star with a mass equal to that of the sun (of mass 1.99 × 10°0 kg) were to collapse into neutrons, what would be the radius of the star? Answer in units of m.arrow_forwardIn a neutron star, gravity causes the electrons to combine with protons to form neutrons. A typical neutron star has a mass half that of the sun, compressed into a sphere of radius 20 km. If such a neutron star contains 6.0 × 1056 neutrons, calculate its density in grams per cubic centimeter.Compare this with the density inside a 232Th nucleus, in which 142 neutrons and 90 protons occupy a sphere of radius 9.1 × 10-13 cm. Take the mass of a neutron to be 1.675 × 10-24 g and that of a proton to be 1.673 × 10-24 g.arrow_forward
- One of the major observations of the nuclear line of stability is that heavy nuclei (Z > 16) that are stable have more neutrons than protons; this is in contrast to light nuclei where the proton and neutron number are the same. Explain why this is the case.arrow_forwardTwo nuclei having atomic numbers Z1 and Z2 approach each other with a total energy E. (a) When they are far apart, they interact only by electric repulsion. If they approach to a distance of 1.00 x 10-14 m, the nuclear force suddenly takes over to make them fuse. Find the minimum value of E, in terms of Z1 and Z2, required to produce fusion. (b) State how E depends on the atomic numbers. (c) If Z1 + Z2 is to have a certain target value such as 60, would it be energetically favorable to take Z1 = 1 and Z2 = 59, or Z1 = Z2 = 30, or some other choice? Explain your answer. (d) Evaluate from your expression the minimum energy for fusion for the D–D and D–T reactions (the first and third reactions in Eq. 43.35).arrow_forwardCompute the gravitational and Coulomb force between two protons in 3He. Assume the distance between the protons is equal to the nuclear radius. The average nuclear potential energy is an attractive 40 MeV effective over a distance of 3.0 fm. Compare that energy with the potential energies associated with the gravitational and Coulomb forces at the same distancearrow_forward
- You are working as a nuclear physicist and are performing research on mirror isobars. Mirror isobars are pairs of nuclei for which Z1 = N2 and Z2 = N1 (the atomic and neutron numbers are interchanged). You wish to investigate the independence of nuclear forces on charge by comparing binding-energy measurements in the laboratory on mirror isobars against a theoretical value for the difference in binding energies. You first find the theoretical difference in binding energies for the two mirror isobars 15/8O and 15/7N.arrow_forwardCopper-63 has a nucleus mass of 62.92959 u. Its atomic number is 29, and its atomic mass number is 63. The mass of a proton is 1.007276 u and the mass of a neutron is 1.008664 u What is the total binding energy of the nucleus? Express your answer in MeV and keep 4 significant digits.arrow_forwardSuppose a cube has a mass of 1.4 kg and the density of nuclear matter (which you can assume is 2.3 × 1017 kg/m3).
