12. Coulomb Excitation of 80Zn

In the summer of 2003, the first Coulomb excitation experiment with post- accelerated and laser ionized even-even Zn isotopes was performed at REX- ISOLDE. Originally the aim was to measure the B(E2) strength to the first excited 2+ state in 74 and 76Zn. In 2006 though, these B(E2) values have been measured up to the "magic" neutron number 50 in the even-even Zn isotopes. In addition,...

3. A New Setup for Transfer Reactions at REX-ISOLDE

Transfer reactions yield important spectroscopic information about isotopes, including spin and parity assignments to nuclear levels and spectroscopic factors. The corresponding information is still lacking for many nuclei far from stability, e.g. in the region of the ``island of inversion'' [1]. A previous experiment [2], studying the d($^{30}$Mg, $^{31}$Mg)p reaction with MINIBALL at...

16. Coulomb Excitation of Neutron-rich Isotopes around A~140

Mr Thomas Behrens (Physics Department E12, TU München)

Recent studies on isotopes around the shell closure at N=82 have shown that despite decreasing excitation energy $E(2^{+}_{1})$ the B(E2;$0^{+}_{1} \rightarrow 2^{+}_{1}$) = B(E2$\uparrow$) values for Te and Sn isotopes above N=82 are lower than expected from a general systematics established as "Grodzins' rule". The aim of the experiment IS411 is to measure the B(E2$\uparrow$) values of...

2. Coulomb excitation of odd-A nuclei 67,69,71,73Cu with Miniball and Rex-Isolde

Ms Stefanescu Irina Stefania (Instituut voor Kern- en Stralingsfysica - KU-University of Leuve)

14/02/2007, 10:30

The low-energy levels in the radioactive neutron-rich odd-A isotopes 67,69,71,73Cu were studied by Coulomb excitation. The results allow a study of the systematic trend across the N=40 subshell closure and the residual proton-neutron interaction when neutrons start filling the g9/2 orbital.
