The He\u00b3 (\u0263,p)D reaction cross section at 8.06 and 9.17 mev  was found to be 0.493\u00b1 0.066 and 0.723\u00b1 0.087 millibarns respectively.  The He\u00b3 (\u0263,n)2p reaction cross section at 9.17 mev  was found to be 0.25\u00b1  0.13 millibarns. These results are compared with other experimental work on the photodisintegration of helium-3 and tritium.\r\nThe photodisintegration reaction was observed in a cylindrical gridded ionization chamber using a helium-3,  methane, and argon gas mixture.  The C\u00b9\u00b3 (p,\u0263) N\u00b9\u2074  reactions at proton bombarding energies of 0.554 and 1.75 mev were used as the source of gamma rays of well defined energy. The preparation of carbon-13 targets is discussed in detail.\r\nTheoretical calculations on the photodisintegration of mass 3 nuclei are summarized.  Photodisintegration and electron scattering measurements are compared as methods of determining the nature of the ground state wave function of the mass 3 system.","language":"en"},{"key":"dc.language.iso","value":"eng","language":"en"},{"key":"dc.publisher","value":"University of British Columbia","language":"en"},{"key":"dc.rights","value":"For non-commercial purposes only, such as research, private study and education.
