Abstract: | The level structure of 153Sm has been studied by means of the 150Nd(α, n)153Sm reaction. The experiment included measurements of the γ-γ coincidences and γ-ray yield as a function of projectile energy. The rotational band built on the [505] Nilsson orbital was observed up to spin , and two ΔI = 2 bands of positive parity were identified with spins up to , respectively. These bands are associated with the single-particle structure.The data obtained in the present work together with data available in the literature are compared to the result of a particle-rotor coupling calculation. The 153Sm nucleus is found to be a wellbehaved rotor. An appropriate single-particle level scheme for 153Sm is established. |
