Neutron Time-of-flight Facility At The University Of São Paulo 8ud Pelletron Tandem Accelerator

A fast neutron time-of-flight spectrometer designed for the 8UD Pelletron tandem accelerator is described. The characteristics of the Pelletron with regard to ion bunching are analyzed. The results of the first order klystron theory calculations are compared with data. Pulse shape discrimination, neutron detection and characteristic neutron time-of-flight spectra are shown. © 1979.1642293303Lawrence, (1972) Proc. 2nd Int. Conf. on Ion sources, , Vienna, AustriaF.J.

The 12c(d, N)13n Reaction Between Ed = 7.0 And 13.0 Mev

Absolute differential cross sections for the n0, n1 and n2 + n3 neutron groups from the reaction 12C(d, n)13N have been measured at incident deuteron energies of 7.0, 9.1 and 13.0 MeV along with an excitation curve at θlab = 25° from Ed = 10.6 to 13.0 MeV. Analysis of energy-averaged cross sections included DWBA calculations and Hauser-Feshbach statistical model calculations. Spectroscopic factors and Hauser-Feshbach reduction factors are obtained and compared to previously reported values. © 1984.41416784Hodgson, (1971) Nuclear reactions and nuclear structure, , Clarendon, OxfordGangadharan, Wolke, (1970) Phys.

Exploring the potential of the São Paulo Potential

Recent development of an imaginary potential based on the São Paulo potential is briefly presented. Further developments of the model in order to describe weakly bound systems (e.g. 7Li +120Sn) are discussed and compared to experimental data. New preliminary data on the 18O+110Pd transitional system are also presented and apparent similarities to the weakly bound case are commented
