Conference paper (peer-reviewed)abstract
- A complete study of the nuclear structure by means of gamma spectroscopy requires, in addition to the high resolution gamma measurement and accurate DCO's or angular distributions, the information concerning the Electric or Magnetic character of the transition. This information for transitions in nuclei far from stability valley is now reachable in the new generation of Ge-arrays based in composite detectors. EUROBALL III is a good example with the high polarization sensitivity of the 90 degrees ring of Clovers. The Polarization correlations PCO's measured in coincidence with the Cluster detectors permits to investigate transitions in weakly populated nuclei. In this contribution we present results on medium mass N=Z nuclei measured with EUROBALL III coupled with light particle ancillary detectors.

Enhanced and quenched B(E1) transition rates between parity doublet bands in Ra-227
- 1996
-
In: NUCLEAR PHYSICS A. - : ELSEVIER SCIENCE BV. - 0375-9474. ; 611:2-3, s. 281-314
-
Journal article (peer-reviewed)abstract
- The fast timing beta gamma gamma(t) method has been used to measure level lifetimes in the parity doublet bands in Ra-227 populated in the beta(-) decay of Fr-227. In particular, T-1/2 = 254(9) ps, 236(30) ps, less than or equal to 41 ps and 16(13) ps hav

-
Journal article (peer-reviewed)abstract
- The fast timing beta gamma gamma(t) method has been used to measure lifetimes of the low-lying levels in Th-231 populated in the beta(-) decay of Ac-231. The half-life of the K-pi = 5/2(-) band-head at 185.7-keV was measured as T-1/2 = 1073(79) ps, yieldi

-
In: NUCLEAR PHYSICS A. - : ELSEVIER SCIENCE BV. - 0375-9474. ; 657:4, s. 355-390
-
Journal article (peer-reviewed)abstract
- The structure of Ra-229 has been studied in the beta(-) decay of Fr-229. Spins and parities have been determined from the conversion electron measurements, while half-lives for the 137.5, 142.7, 168.8, 213.0 and 479.0 keV levels have been measured in the

In: NUCLEAR PHYSICS A. - : ELSEVIER SCIENCE BV. - 0375-9474. ; 636:1, s. 28-46
-
Journal article (peer-reviewed)abstract
- Spins and parities for collective states in Ra-228 have been determined from conversion electron measurements with a mini-orange beta spectrometer. The fast-timing beta gamma gamma(t) method has been used to measure lifetimes of T-1/2 = 550(20) ps and 181
