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).

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.

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”)
