Question
The unexpected stability around magnesium-32, known as an “island of inversion,” is associated with the presence of this phenomenon in the ground state. For 10 points each:
[10h] Name this phenomenon that Aage (“AW-wuh”) Bohr used to explain certain nuclear quadrupole moments.
ANSWER: nuclear deformations [accept answers describing non-spherical nuclei]
[10e] Islands of inversion are found near these neutron numbers. Using the shell model, Maria Goeppert Mayer predicted these numbers that correspond to full nuclear shells.
ANSWER: magic numbers
[10m] Bohr investigated deformation properties of nuclei using a combination of this model of the nucleus, proposed by Gamow, and the shell model. The semi-empirical mass formula can be obtained from this model.
ANSWER: liquid-drop model
