Question by Giancoli, Douglas C., Physics: Principles with Applications, 7th Ed., ©2014, Reprinted by permission of Pearson Education Inc., New York.
Problem 21
Q
  1. Show that the nucleus 48Be{^{8}_{4}\textrm{Be}} (mass = 8.005305 u) is unstable and will decay into two α\alpha particles.
  2. Is 612C{^{12}_{6}\textrm{C}} stable against decay into three α\alpha particles? Show why or why not.
A
  1. Negative binding energy means 48Be{}^8_4Be is unstable
  2. A positive binding energy means 612C{}^{12}_6C is stable against decay to 24He{}^4_2He
