EURICA Workshop

The proposal deals with study of doubly - magic 100Sn and neighboring nuclei via measurement of their beta- and isomeric-decay. Very high production rates, which should be achievable at the RIBF/BigRIPS facility for nuclei in the vicinity of 100Sn together with the EURICA Germanium setup, open new possibilities for the decay spectroscopy. The main goals of the experiment are: measurement of...

Recent work at GSI has enabled us to obtain evidence for the 16+ spin-gap isomer in 96Cd via its beta decay to the 15+ isomeric state in 96Cd. However, large scale shell model calculations using the gds model space indicate that the state should also undergo beta-delayed proton decay. Our previous data did not have sufficient statistics to enable us to search for such decays. It is...

We have studied the Tz = -1 -> 0 beta decays of 42Ti, 46Cr, 50Fe and 54Ni to the self-conjugate nuclei 42Sc, 46V, 50Mn, and 54Co respectively (Ph.D Thesis, Francisco Molina- Uni. Valencia) at GSI during the stopped beam RISING campaign. The nuclei of interest were produced in the fragmentation of a 58Ni beam at 680 MeV/nucleon. The number of implanted ions of the nucleus of interest was...

It is well known that in the atomic nucleus, alike nucleons (neutrons or protons) in time reverse orbits, couple in pairs giving rise to nuclear superfluidity, with very significant impact in the structure as well as in the collective properties of the nucleus. In addition, nuclei consist of a combination of two fermionic fluids (neutrons and protons) and as a consequence of the isospin (T)...

An experiment based on gamma-decay of isomer state in neutron-rich 77Ni produced from fragmentation of a 238U beam is proposed in order to reveal the neutron single particle energies associated with the N=40 and N=50 shell closures. Based on the lifetime of the 1/2- isomeric state in 77Ni an estimate or at least a lower limit on the energy of the 2+ state in 78Ni can be deduced. Energy and...
