14 MeV neutron reactions producing gamma-ray emitting nuclides with half-lives below 3 seconds

Fast neutron activation analysis (FNAA) experiments were performed using a Cockroft-Walton neutron generator and a fast pneumatic rabbit system with a sample transport time of 120 ms. With this facility cyclic activations of¹⁸O, Zr, Ba and Pb leading to the short-lived reaction products¹⁵C,^90mZr,^136mBa and^207mPb were investigated. Derived from these measurements the analytical sensitivities of the involved reactions will be discussed.
