| Abstract: | We have measured the differential cross sections for the reactions 12C(τ, τ′)12C(17.77 MeV 0+T=1) and 12C(τ, t)12N(2.43 MeV) at Eτ=44 MeV. The similar shapes of the angular distributions and the relative magnitudes of the cross sections suggest that the 12N 2.43 MeV level is the 0+T=1 analog to the q12C 17.77 MeV level. We have also studied the reaction 14N(p,t) 12N(2.43 MeV) at Ep=52 MeV. The strength with which this level is excited in this reaction is consistent with reasonable two-step calculations assuming the 2.43 MeV level to have Jπ=0+. |
