Triaxiality in Neutron-Rich Nuclei with A ˜ 100-126, Z Beyond and Below Ru (Z=44)
This paper reviews the systematic investigations of the shape transitions and coexistence with regard to triaxial deformations in neutron-rich nuclei with A ˜ 100-126, Z from Zr (Z = 40) to Cd (Z = 48). Shape changes with Z, N and spins are addressed. γ vibrations, chiral symmetry breaking and wobbling motions identified in the region are discussed.
