The differential cross sections for elastic scattering of deuterons from l 6 0 have been measured in the Ed = 1.0. -. 2.5 MeV region at eight scattering angles. Resonances were observed at Ed = 1.00, 1.80 and 2.45 MeV, corresponding to the excited states in I8F at 8. 40, 9.11 and 9.69 MeV. Analysis of the data in terms of the single-level approximation leads to the assignments I" = 1+, 3+ and 2+, respectively. Reduced partial widths for elastic scattering were determined.

The yield curves of the (d, p) and (d, a) reactions on 3lp nucleus are measured in 10 keV steps from 2.000 up to 2.500 MeV deuteron energy. The analysis of the measured' cross-section fluctuations is car¡ out in terms of the EmCSON theory of statistieal fluetuations. The average coherence width F obtained amounts to 20 -Ÿ 5 keV for the 33S compound nucleus at ah energy of excitation of 17.396 MeV, yielding a life time ~ = 3.0 x 10-2~ sec. The absence of correlation between the different emitted groups and channels of decay of the 33S compound nucleus is confirrned. Probability distribution of the cross section around their average is found to obey a X2-distribution with 2N degrees of freedom (with N the effective channel number). I. lntroduetionThe (d, p) and (d, ~) reactions on 31p targets were studied by many authors [1--4], in the deuteron energy range from about 1.0 up to 4.0 Meu where the angular distributions of the emitted protons and alpha groups were measured, in an attempt to investigate the reaction mechanisms,especially that of the statistical theory. In the deuteron energy range from 7.0 up to 12.0 MeV, the (d, ~) reaction on 31p was investigated [5], and the results were analyzed in terms of the ERicsoN theory of statistical fluctuation [6].In the higher energy ranges, these reactions were investigated and analyzed by applying the DWBA theory of direct reactions [7,8].In the present work, the excitation functions of the (d, p) and (d, ~) reactions on 31p targets are measured in the deuteron energy range from 2.0 up to 2.5 MeV in order to investigate the compound nucleus contribution to the reaction mechanism. The results ate analyzed by applying the ERIcSOr~ theory of the statistical fluctuations [6].

The reaction MgZ5(d, a)NaZ3 has been studied a t bombarding energies between 1.5 and 2.5 MeV. Excitation functions for the ground and the lowest six excited states were measured a t laboratory angles of 120°, 140" and 160". The energy resolution in the measurements was better than 10 keV. Fluctuations in these cross-sections were analysed on the basis of the ERICSON theory. The coherence width of the compound nucleus AlZ7 (with excitation energy 19 MeV) averaged over all transitions has been found t o be 29 keV.From the analysis of the probability distributions of fluctuations. the number of independent magnetic substates was found to be less than that predicted by the theory. Numerous group-cross correlation functions for (d, p ) and (d, (x) reactions on MgZ5 were analysed.
