Abstract

The nuclear shell-model calculations show a clear anticorrelation between the Gamow-Teller strength and the transition rate of the collective quadrupole excitation from the ground state in response to artificial changes of the spin-orbit splitting. The shell-model calculations in the fp space demonstrate that changes of the spin-orbit coupling influence Gamow-Teller and quadrupole modes in the opposite way. This interrelation is discussed in terms of simple symmetry arguments.
