Abstract

The photodisintegration of ¹⁵N through excited states of the residual nuclei has been studied by measuring the yields of de-excitation gamma rays in a Ge(Li) detector. Cross sections for all observed transitions were deduced from measurements with bremsstrahlung end-point energies ranging from 15 to 35 MeV and account for an integrated cross section of 44 MeV mb. Bound states in ¹⁴N and ¹⁴C with a dominant (1p₁2/)^-1 or (1p₃2/)^-1 configuration are found to be strongly populated. The nature of the states in the ¹⁵N giant resonance is discussed. The ¹⁵N( gamma ,t)¹²C* (4.44 MeV) reaction was also observed and its integrated cross section is approximately 5% of the expected value of the E1 sum rule.
