(Leuven U.) ; Delaroche, J.P. (CEA DAM) ; Dobaczewski, J. (York U., England ; Warsaw U.) et al.
We employed laser spectroscopy of atomic transitions to measure the nuclear charge radii and electromagnetic properties of the high-spin isomeric states in neutron-rich indium isotopes (Z = 49) near the closed proton and neutron shells at Z = 50 and N = 82. Our data reveal a reduction in the nuclear charge radius and intrinsic quadrupole moment when protons and neutrons are fully aligned in 129In(N = 80), to form the high spin isomer. [...]

Measurement of lifetimes in $^{62,64}$Fe,$^{61,63}$Co , and $^{59}$Mn
/ Klintefjord, M (Oslo U.) ; Ljungvall, J (CSNSM, Orsay) ; Görgen, A (Oslo U.) ; Lenzi, S M (INFN, Padua ; Padua U.) ; Bello Garrote, F L (Oslo U) ; Blazhev, A (Cologne U.) ; Clément, E (GANIL) ; de France, G (GANIL) ; Delaroche, J P (CEA DAM) ; Désesquelles, P (CSNSM, Orsay) et al.
Lifetimes of the 41+ states in 62,64Fe and the 11/21− states in 61,63Co and 59Mn were measured at the Grand Accélérateur National d'Ions Lourds (GANIL) facility by using the Advanced Gamma Tracking Array (AGATA) and the large-acceptance variable mode spectrometer (VAMOS++). The states were populated through multinucleon transfer reactions with a U238 beam impinging on a Ni64 target, and lifetimes in the picosecond range were measured by using the recoil distance Doppler shift method.

The structure of low-lying states in ${}^{140}$Sm studied by Coulomb excitation
/ Klintefjord, M. (Oslo U.) ; Hadyńska-Klȩk, K. (INFN, Legnaro ; Oslo U.) ; Görgen, A. (Oslo U.) ; Bauer, C. (Darmstadt, Tech. Hochsch.) ; Bello Garrote, F.L. (Oslo U.) ; Bönig, S. (Darmstadt, Tech. Hochsch.) ; Bounthong, B. (Strasbourg, IPHC) ; Damyanova, A. (Geneva U.) ; Delaroche, J.P. (CEA DAM) ; Fedosseev, V. (CERN) et al.
The electromagnetic structure of $^{140}$Sm was studied in a low-energy Coulomb excitation experiment with a radioactive ion beam from the REX-ISOLDE facility at CERN. The $2^+$ and $4^+$ states of the ground-state band and a second $2^+$ state were populated by multi-step excitation. [...]
