摘要
The reactions B11(He3,n)N*13 (T=32) (γ) and B11(He3,p)C*13 (T=32) (γ) have been used to study the γ-decay modes of the lowest T=32 states in N13 and C13. Coincidences between neutrons and associated γ rays in the case of N13 and between protons and γ rays in the case of C13 were recorded in a two-dimensional array. For the γ decay of N13(15.07) and C13(15.11), we find Γγ0Γp0=(12±2)% and Γγ0Γ=(0.53±0.06)%, respectively. When combined with previously available experimental information, these values yield Γ=1.13±0.3 and 4.7±1.6 keV for the first T=32 levels in N13 and C13, respectively. Additional information on γ branching ratios and particle decay for these levels is presented. © 1968 The American Physical Society.
