Cross Sections for Neutron Inelastic Scattering on 28Si

A measurement of the neutron inelastic cross sections on 28Si was performed at the GELINA (Geel Linear Accelerator) white neutron source of EC-JRC-IRMM, Belgium. The GAINS (Gamma Array for Inelastic Neutron Scattering) detection system was used to determine the production cross sections of the most intense gamma rays. The neutron flux was monitored with a 238U fission chamber. Using the level scheme from the ENSDF database, the total inelastic cross section and the level production cross section of the first levels were determined. A few gamma production cross sections from the (n,p) and (n,alpha) channels were also measured. The results are compared with previous existing data and with the results of theoretical calculations performed with the TALYS 1.2 reaction code.JRC.DG.D.5-Nuclear physic
