ts) 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?
The difference in the coulomb energy between the mirror nuclei (_24^49)Cr and (_25^49)Mn is 6 MeV. Assuming that the nuclei have spherically symmetric charge distribution and that e^2 is approximately 1.0 MeV-fm. Find the radius of the (_25^49)Mn Nucleus.
Mg, dMg are all stable. Draw energy-level diagrams for these nuclei and use the dia
grams to explain how it is possible that all three of these nuclei are stable. Can you say for certain
that electrostatic repulsion is significant here?
