The Miniball germanium array has been in use at REX-ISOLDE for more than six years now. Over these years, Coulomb excitation experiments have been performed on a variety of isotopes ranging from Mg (Z=12) to Rn (Z=86). Many of these Coulomb excitation experiments aim at the study of shell evolution far off the line of beta stability by measuring transition probabilities between low lying...

One of the remarkable properties of the nucleus is its ability to minimise its energy by adopting different deformed nuclear shapes. In some cases, this can lead to competing minima very close together. This phenomena has been widely tracked through the neutron-deficient lead, mercury and platinum isotopes, where the shape coexistence has been discussed in terms of intruder states based on...

In light, even mass Hg isotopes, a weakly deformed oblate ground state band is found to coexist with a more deformed prolate band. To investigate the origin and evolution of shape coexistence in the N = 102-108 mid shell region Coulomb excitation measurements of 182,184,186,188Hg were performed at REX-ISOLDE using the MINIBALL detector array. The radioactive Hg beams were provided by ISOLDE...

The wave-function composition for the low-lying states in 29Na was explored by measuring their electromagnetic properties using the Coulomb-excitation technique. A beam of radioactive 29Na ions, postaccelerated to 70 MeV using ISAC-II at TRIUMF, bombarded a 110Pd target with a rate of up to 600 particles per second. Six segmented clover detectors of the TIGRESS gamma-ray spectrometer were...
