NUCLEAR REACTIONS ¹⁴⁸Nd(⁷Li, 4n)¹⁵¹Eu, E=30 MeV; measured Eγ, Iγ, γγ-coin γγ(θ). ¹⁵¹Eu; deduced levels, J, π, high-spin states, directional correlation of oriented states (DCO) ratio, polarization asymmetries, mixing ratios, δ, rotational bands structure, B(E2_in)/B(E2_out), B(M1_in)/B(E2_out). Comparison to triaxial projected shell model calculations. Evidences of presence of transverse wobbling in ¹⁵¹Eu. Systematics of wobbling excitation energies for ¹⁵¹Eu, ¹³⁵Pr, ¹³³Ba, ¹⁸³Au, ¹⁸⁷Au, ¹³³La and ¹²⁷Xe. Indian National Gamma Array (INGA) consisting of 16 Compton suppressed clover detectors and 2 ancillary LEPS detectors at 15 UD pelletron (IUAC, New Delhi).
