Carbon 12C(alpha, alpha) 12C*[i.e. Carbon 12 (alpha alpha prime) carbon 12] and 10B([alpha]d)12C* reactions to the T=0 12.71 mev and T=1 15.11 mev states in 12C Spuller, Joseph
Abstract
The yields of the reactions 12C(α, α ')12C* to the T=0
state at 12.71 MeV (Jπ=1+ ) and the T=l state at 15.11 MeV
(Jπ=1+ ) were measured by detecting the decay of these levels
to the ground state by gamma emmission. A 90° (lab) yield
curve from threshold to Eα= 27.0 MeV was obtained for each
reaction. Both states have to be populated via an unnatural
parity process and in addition the population of the 15.11
MeV level is isospin forbidden. Nevertheless, excitation of
both levels is unambiguously detected. Although the ratio of
the yields has a considerable energy dependence ( 1%
