Lifetime measurement in 122^{122}Ba and 122^{122}Cs using Doppler Shift Attenuation Method (DSAM)

International audienceThe nuclear structure exhibits transitional behaviour in the A'125 mass region as the nuclei lie between the spherical (Sn, Z=50) and deformed (Ce, Z=58) structures. Here exists a unique parity intruder subshell, h11/2, which can be accessed by both the protons and the neutrons. These h11/2 nucleons have opposite deformation driving effects which lead to an interplay of prolate, oblate or triaxial nuclear shapes[1]
