Abstract
The nucleus16O has been investigated within the excitation range of 25–32 MeV by means of the reaction13C(τ, α)12C* 15.1(γ)12C. Excitation functions for the 15.1 MeVγ-rays, taken for bombarding energiesE τ=2.6–12 MeV at 0‡ and 90‡, exhibit some marked structures with widths of 0.5 to 1 MeV. As the (τ, α)-reaction leads to the 15.1 MeV,T=1 state, levels in16O underlying these structures should have largeT=1 components. Angular distributions of theα-particles coincident to the 15.1 MeVγ-rays show patterns typical for a direct process and are, therefore, compared with DWBA calculations.
