1.1. Analysis of neutron resonances
C. Coceva, F. Corvi, P. Giacobbe and M. Stefanon
A work describing the experimental and analysis methods employed
for the determination of slow-neutron resonance parameters has
been accepted for publication on Nuclear Instruments and Methods.
The abstract is the following: Methods of analysis of neutron
transmission data in time-of-flight spectrometry are examined,
with particular attention to the experimental conditions which
should be satisfied for a correct estimation of resonance
parameters and errors. To improve the applicability of the
shape-analysis method in the work performed with the fast neutron
chopper of Ispra, the resolution function of this spectrometer
was determined in a detailed way.
The main features of the analysis methods applied to the experi­
mental data obtained at Ispra are presented and illustrated by
examples.
2.1. Spin assignement of neutron resonance
(*)
C. Coceva, F. Corvi, P. Giacobbe and G. Carraro
These measurements have been performed at the Linac of the
C.B.N.M. Euratom, Geel (Belgium); an account of them can be
found in the chapter C.B.N.M. activities.
3.1. Numerical simulation of the y-ray cascade
