Some Current Themes in Nuclear Research

Abstract
The topics covered include: (a) Elementary modes of excitation with special emphasis on the isoscalar highfrequency quadrupole vibrations. (b) Conditions for shell structure in both spherical and deformed potentials. (c) Modifications in nuclear structure produced by large angular momentum, including a discussion of stability conditions as well as of the spectrum of quantum states in the yrast region for very large angular momentum.
