Abstract :
High spin states of 155Gd have been investigated using the 150Nd(12C, α3n) reaction. Three rotational bands have been observed. Two of them have been extended up to (51/2)+ and 45/2−, respectively, and another band has been newly observed. The backbending and blocking effects are discussed in comparison with the calculation of cranked shell model. The routhians and the B(M1/BE2 ratio of the high-Ω rotational band are compared with the calculation by the tilted axis craking model. In addition the ground state rotational band of 156Gd has been extended up to 22+.
