mental data obtained and presented for these reactions consist of angular distributions at bombarding energies from 5.6 to 6.6 MeV at 200-keV intervals and at 9.0, 10.0, 11.2, 12.0, 13.0, and 14.0MeV, and of yield curves at (9&b=0' and 40'. In addition, an angular distribution of Li' elastically scattered from C" was obtained at a bombarding energy of 13.0 MeV for use in determining opticalmodel parameters for the Li'+C" entrance chan-
nel.A comparison has been made of the results of the experiment and predictions of direct-reaction and statistical compound-nucleus models.
Using a double-coil, thin-lens magnetic beta-ray spectrometer of transmission 2.40 percent and line width of approximately 3.0 percent, the internal conversion coefficients of the gamma-rays from Co 60 , Cs 134 , and Zn 65 have been measured. Sufficient precision has been attained in several cases to verify the theoretical values and to obtain unambiguous identification of the multipole character of the gamma-rays. Internal conversion coefficients as small as 10~6 can be measured with a precision of 5 percent or better.The results obtained indicate that both of the gamma-rays from Co 60 are electric quadrupole (EQ), the 560-kev gamma-ray from Cs 134 is either EQ or MD or a mixture of these, the 602-and 799-kev gamma-rays from Cs 134 are both EQ, the 1.114-Mev gamma-ray from Zn 65 is either EQ or MD or a mixture of these and the 1.363-Mev gamma-ray from Cs 134 may be EQ. Further data on the decay scheme of Cs 134 are given.The results show that in combination with angular correlation measurements internal conversion data determine the angular momenta and parities of excited nuclear states.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
