Skyrme random-phase-approximation description of lowest K^π = 2⁺_γ states in axially deformed nuclei

NUCLEAR STRUCTURE ^150,152Nd, ^152,154,156Sm, ^{154,156,158,160}Gd, ^{158,160,162,164,166}Dy, ^{162,164,166,168,170}Er, ^{168,170,172,174,176}Yb, ^{168,170,172,174,176,178,180}Hf, ^{178,180,182,184,186}W, ^{232,234,236,238}U; calculated energies and B(E2) of the lowest quadrupole γ-vibrational Kπ=2+ states in axially deformed rare-earth and uranium even-even nuclei. ¹⁵²Nd, ¹⁶⁴Dy, ¹⁷²Yb, ²³⁸U; calculated isoscalar strength function for the ISGQR. Separable random-phase-approximation (SRPA) method based on the Skyrme functional with the Skyrme forces SV-bas and SkM*, and corrected by using pairing blocking effect. Comparison with experimental data.
