Description
Studying transfer-induced fission in inverse kinematics offers advantages over neutron-induced fission measurements in normal kinematics. Two such advantages include the ability to measure fission barrier heights of fissile nuclei due to the addition of a third body to the system, and the possibility to study the fission properties of short-lived actinides where fixed targets are not feasible; these appealing features have been exploited in the past [1-2].
The approach that we are currently investigating is to use the single neutron-adding (d,p) reaction as a precursor to fission. With a solenoidal spectrometer such as the ISS coupled with a fission fragment detection array composed of Bragg chambers, measurement of the following parameters should be possible: fission barrier height, mass and charge yields, and by measuring fission probabilities as a function of excitation energy, the corresponding neutron-induced fission cross section can be deduced. By measuring the angular distribution of the outgoing (d,p) protons, the dependence of fission probability on spin can also be investigated.
The feasibility for the measurement of the aforementioned quantities has been demonstrated by means of simulation, the results of which shall be presented. Calculations of transfer-induced fission rates based on ISOLDE target yields will also be presented to indicate the most viable cases, and where beam development would be beneficial to the project.
