LABORATORIO DI FÍSICA NUCLEARE APPLICATA, CENTRO DI STUDI
NUCLEARI DEL C.N.E.N., CASACCIA (ROMA) (ITALY)
Introduction
In the last year the Nuclear Physics Group of the "Centro Studi
Nucleari della Casaccia" was engaged in the following activities:
1) Nuclear resonant scattering experiment.
2) Gamma-ray spectroscopy and thermal neutron radiative capture
experiment.
3) (n,n*Y) directional correlation measurements on Mg and Si.
4) Development of techniques for the elaboration of experimental
data with computers.
5) Theoretical studies on the nuclear wave functions.
Later on the progresses we obtained in this year will be briefly
described.
Experimental studies
The running of the TRIGA Mark II reactor of the "Centro Studi
Nucleari della Casaccia" (Applied Nuclear Physics Laboratory)
was stopped in September 1965 for a power increasing from 100 kW
to 1 MV.
In this occurrence a new facility was planned and executed,,con­
sisting in a beam hole tangential to the reactor core and going
through the whole biological shield. The main features of this
new facility were described in our preceding reports.
The reactor will work again regularly at the beginning of 1968.
However some preliminary measurements have been performed in
the last months.
Nuclear resonant scattering experiment
The aim of nuclear resonant scattering experiments is both to
measure the radiative widths of nuclear levels with energy near
to the binding energy for particles emission and to study in-
