Popis: The transitional nucleus 154Gd was investigated using a combination of a photon scattering experiment and a γγ-coincidence study following the β decay of 154Tb. A novel decay channel from the scissors mode to the band head of the β-band was observed. Its transition strength B(M1; 1sc+ → 0β+) was determined. An IBM-2 calculation reveals a correlation of this decay channel and the shape phase transition between spherical and deformed nuclei.
