(3He, d) and (α, t) reaction studies of 154Gd: nature of Kπ=4+ bands in heavy deformed nuclei

Levels in 154Gd have been studied with (3He,d) and (α,t) reactions using beams of 24 MeV 3He and 27 MeV α particles. Particle spectra were measured with a magnetic spectrograph at θ=30° and 60° for the (3He,d) and at θ=45° and 60° for the (α,t) reaction. Cross sections were compared with predictions based on Distorted Wave Born Approximation and Nilsson model calculations. The γ-vibrational band has an admixture of ∼15% of the …
