Longitudinal wobbling in ¹³³La

NUCLEAR REACTIONS ¹²⁶Te(¹¹B, 4n)¹³³La, E=52 MeV; measured Eγ, Iγ(θ), γγ-coin, γγγ-coin using INGA (21 Compton suppressed HPGe coupled with digital data acquisition system); deduced ¹³³La lower levels, J, π, γ transitions, angular distribution plots for pure 758, 874, 982 keV M1 transitions in coincidence with 445 keV transition, perpendicular and parallel spectra, a₃₂-a₄ contour plots, Direction Correlation from Oriented states (DCO) ratio spectra, B(E2)_in, B(E2)_out, B(M1)_out γ-transitions strengths, mixing ratios, wobbling bands with n_ω=0 and 1 with interconnecting E2 transitions, increase of wobbling of frequency; calculated ¹³³La angular distribution plots, a₂-a₄ contour plots, Direction Correlation from Oriented states (DCO) using Quasiparticle-Triaxial-Rotor (QTR) model with and without Harmonic Frozen Approximation (HFA) theory, Tilted Axis Cranking (TAC) model; deduced longitudinal wobbling for ¹³³La. Data compared with recently published ¹³³La study using ¹¹⁶Cd(²²Ne, x) at Gammasphere.
