- (a) Show that if you assume the average nucleus is spherical with a radius r=r0A1/3, and with a mass at A u, then its density is independent at A. (b) Calculate that density in u/fm3 and kg/m3, and compare your results with those found in Example 31.1 for 56Fe.arrow_forwardts) We can approximate the 232Th nucleus as a one-dimensional infinite square well with length L equal to the nuclear radius R = R₁A¹/3, where Ro = 1.2 fm and A is the atomic mass number. (a) What is the length of this infinite square well? What is the ground state energy of a proton (which has mass m₂ = 938.3 MeV/c²) in this infinite square well? (b) 232Th has 90 protons and 142 neutrons. Assume that all these protons and neutrons trapped in the infinite square well. How many energy levels of this infinite square well contain protons? How many energy levels contain neutrons?arrow_forwardYou 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_forward
- You have been hired by a "storm chaser" as an assistant. This individual loves to find locations at which tornadoes and violent lightning storms are occurring. While there, he takes photographs and makes electromagnetic measurements. You and he are observing a massive lightning storm in Oklahoma. The storm chaser has a new theory that nucleus-free atoms are formed for the very short time interval during a lightning strike. He asks you to evaluate his theory, which goes something like this: In a long, straight, vertical lightning stroke, electrons move downward and positive ions move upward and constitute a current of magnitude I. At a location in the air a distance R from the middle of the stroke a free electron drifts through the air toward the stroke with a speed v. While the current in the lightning stroke exists, a strong magnetic field exists at the position of the electron and causes it to move in a circular path like that in the figure below, with its plane perpendicular to the…arrow_forwardUse the semiempirical mass equation to compute, for given A, the relation between Z and N for a nucleus that has Sn 4 0 (the neutron "drip line").
