Abstract

The inelastic scattering of 81.6 MeV deuterons has been studied on sixteen levels up to 13.8 MeV excitation energy in ¹⁶O. The experimental angular distributions have been compared with DWBA predictions within the framework of the collective model. The addition of an imaginary term is found to be necessary to account for the angular distribution shape of the collective transitions at small angles. Deformation parameters have been extracted for the collective states.

Nuclear interactions for medical purposes
1981, Progress in Particle and Nuclear Physics
The purpose of this review is to introduce the reader to some areas of application or potential application of nuclear physics in medicine. The emphasis is on new developments, such as the use of charged particles in radiography and tomography, and the use of pions and heavy ions in therapy. It is shown that understanding of the physical processes underlying these applications is far from adequate in many cases and that there is a surprising lack of information on nuclear reactions on common light nuclei such as carbon and oxygen.
The 16O(d, 3He)15N reaction at 29 MeV: Reaction mechanism and nuclear structure
1976, Nuclear Physics, Section A
The reaction ¹⁶O(d, ³He)¹⁵N has been investigated using 29 MeV deuterons, and angular distributions were obtained for levels in ¹⁵N up to 10 MeV excitation energy. The measured distributions were subjected to distorted-wave (DWBA), compound nucleus (Hauser-Feshbach) and coupled-channel (CCBA) analyses. Only the strong transitions to the $12$ ⁻ ground state and the $32$ ⁻ state at 6324 keV exhibit distributions which are well described by DWBA. The spectroscopic factors are in agreement with shell-model estimates. The weak transitions generally show little structure and the spectroscopic factors extracted for these transitions tend to be unreasonably large. Contributions from compound nucleus formation were estimated and found to vary between about 10 % and 100 % of the observed cross sections with an average of the order of 30 %. The CCBA analysis for the transitions to the $521^{+}$ , $522$ ⁺ and $72$ ⁺ states at 5271, 7155 and 7566 keV, respectively, was performed using the spectroscopic amplitudes from weak coupling shell-model wave functions. Inelastic excitations to one-phonon states in the target and residual nuclei were included. The agreement between calculated and experimental distributions is good for both shape and magnitude, a conclusion which is not disturbed by the addition of small compound nucleus contributions. It is evident that spectroscopic factors extracted for the weak transitions on the basis of a direct one-step reaction mechanism alone are unreliable.
