Multiphonon γ-vibrational bands in the γ-soft nucleus ¹³⁸Nd

NUCLEAR REACTIONS ¹²⁴Te(¹⁹F, 4np), E=103 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ)(DCO) at CIAE facility. ¹³⁸Nd; deduced levels, J, π, multipolarity, multiphonon γ-vibrational bands, γ softness; calculated bandhead energies as a function of triaxiality. Comparison with cranked shell-model and, triaxial projected shell-model calculations. Systematics of bandhead energies of one- and two-γ vibrational bands in ^104,106Mo, ¹³⁸Nd, ¹⁵⁴Gd, ¹⁶⁸Er.
