Abstract

A method has been developed for preparing thin films of carbon on tantalum, and the thick and thin target yields of the (p,γ) reactions for C¹² and C¹³ targets studied for proton energies of 0.4 to 2.7 MeV.

With C¹³ enriched targets, five resonances were found, corresponding to levels in N¹⁴ at 8.05, 8.62, 8.70, 9.18, and 9.49 MeV. The radiation spectrum from these levels has been investigated and found to involve several branches of decay, and transitions cascading through intermediate levels.
