The precise determination of the neutron capture cross sections of 186Os and 187Os is important to define the s-process abundance of 187Os at the formation of the solar system.

This quantity can be used to evaluate the radiogenic component of the abundance of 187Os due to the decay of the unstable 187Re (t1/2 = 41.2 Gyr) and from this to infer the time duration of the nucleosynthesis in our galaxy (Re/Os cosmochronometer).

12C(a,)16O 13C(a,n)16O 22Ne(a,n)25Mg (a,) reactions on 14,15N and 18O

CSN3Conclusions - 1

ALICE is collecting data with p and producing papers. Ready for further Pb-Pb data taking.

The first experimental campaign with the AGATA demonstrator has started at LNL. The realization of ¼ of solid angle is in progress. Nuclei at extremes and more degrees of freedom will be investigated.

Esperiments engaged in upgrades (such as JLAB and CHIMERA at LNS) are progressing.

Several relevant results are obtained with the analysis under way. They are important to guide the future programs.

Improvements to the national infrastructures are in progress.

CSN3Final Remarks

The Italian Nuclear Physics Community is providing high quality results taking also advantage of the national facilities

There are several foreseen upgrades, particularly ALICE, that will stress the financing capabilities of CSN3

PANDA could also overload the CSN3 and requires a wise decision

There are, at present, two major investment in the National Laboratory infrastructures (SPES and LUNA-MV) that requires a large amount of money (INFN applied to the Governement “Fondi Premiali”)
