# Rutgers Physics 418 Nuclei & Particles (Somalwar)

## Homework 2 - Due September 29, 2017

Das & Ferbel refers to the textbook *Introduction to Nuclear and
Particle Physics, ***2nd **
Edition, by A. Das and T. Ferbel

Syllabus

Special topic: Mossbauer Effect: (To be) covered in class.

Entire Chapter 4: Read the couple of topics not covered in
class on your own. They will be covered later.

1) Das & Ferbel, Problem 4.2. (Review impact parameter etc from Ch.1.
In particular, note that the impact parameter is NOT the distance of closest
approach. Drawing a diagram might help.)

2) Das & Ferbel, Problem 4.3. (Don't go crazy deriving general purpose
formulae, but think about the relative masses of the three objects and
which quantities are important and
which can be ignored. Also think about the extreme cases. For the max proton
energy, think of the electron and neutrino as a combined system and figure out
when it will carry the least energy. Always go back and check your
assumptions, of course. Answers: proton: 0.752KeV, electron/neutrino: 782KeV.)

3) Das & Ferbel, Problem 4.6.

4) Das & Ferbel, Problem 4.7. [There could be a typo in your copy of the
text. The coefficient should be 0.015, not 0.008. Also, you might want to
quickly read up the section on fission from Chapter 5, specifically, equation
5.8]
