Angular Distributions of Some γ-rays Produced in Nuclear Reactions


Day, Robert Briggs (1951) Angular Distributions of Some γ-rays Produced in Nuclear Reactions. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/mfsw-2m02.


Measurement of the angular distributions of they-rays produced in nuclear reactions promises to be a fruitful method in helping to determine the spins and parities of the nuclear states involved. The methods and apparatus for doing this for proton reactions on light nuclei are described. Results are given for the following reactions: F19(p,αγ)O16 at various resonances between 850 and 1400 kev, C12(p,γ)N13 at the 1696 kev resonance, and C13(p,γ)N14 at the 1754 kev resonance. A short account is given of the principles involved in the calculation of angular distributions. This is followed by a discussion of the experimental results in terms of the spins and parities of the states. For the fluorine reaction this has already been done by Chao. The C12(p,γ)N13 resonance seems to be due to a compound nucleus with spin 3/2 and even parity. For the C13(p,γ)N14 resonance the theory does not permit a definite assignment to be made on the basis of this experiment.
