A Study of the T(d,γ)^5He Reaction


Batay-Csorba, Peter Andrew (1975) A Study of the T(d,γ)^5He Reaction. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/77EQ-NB39.


The cross section for the reaction, T(d,γ)5Heg.s., has been measured over the range of deuteron bombarding energies extending from 2 MeV to 12 MeV. A solid ZrT target was employed, and the cross sections were normalized by comparison with the well-known cross sections for the T(d,γ)4Heg.s. reaction. A well shielded, 8" diameter by 5" long NaI(Tl) crystal, 31" from the target, was used to detect the capture γ-radiation. Time-of-flight techniques were employed to suppress cosmic-ray background and neutron background arising mainly from the T(d,n)4He reaction. Serious pulse pile-up problems were encountered because of an intense flux of lower energy gamma rays arising mainly from contaminants in the target.

For a set of optical model potentials that describe the T + d differential elastic scattering, the direct radiative capture cross section for T(d,γ)5He was calculated. Although the cross section is under-predicted by about a factor of two, the calculated energy dependence of the cross section is similar to that observed.
