Physics 5110, Spring 2020 Homework #4 Due in class Wednesday February 5 th 1. Using the Bethe-Weizs¨ acker semi-empirical mass formula, plot the binding energy per nu- cleon of nuclei with A = 29 as a function of the nuclear charge Z . Let Z range from 8 to 21. What value of the nuclear charge corresponds to the most stable nucleus? Does this agree with observation? 2. Calculate the binding energy of the last neutron in 4 He and the last proton in 16 O. How do these compare with B/A for these nuclei? What does this tell you about the stability of 4 He relative to 3 He, and of 16 O relative to 15 N? Hint: the binding energy of the last neutron needed to form a nucleus ( A,Z ) is given by [ M ( A - 1 ,Z ) + m n - M ( A,Z )] c 2 . An analogous expression holds for the last proton. 3.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
