Abstract
The even-even nucleus ¹²⁸Nd was studied via in-beam -ray spectroscopy using the ⁴⁰Ca +⁸²Mo reaction at 190 MeV. Two new bands were observed besides the yrast one, that has been extended up to spin 34⁺. Configurations were assigned to the three bands by analysing their rotational properties and by comparison with the neighboring even-even nuclei.
