Description
The role of new nuclear-physics experiments in the creation of nuclear databases and development of theoretical models in accordance with modern approaches is key in both fundamental and applied researches related in particular to the development of electro-nuclear plants (Accelerator Driven System, ADS) for the nuclear transmutation of long-lived radioactive nuclear waste and energy production [1,2].
The experiments with protons accelerated to energy of 7 and 30 MeV were performed on an isochronous cyclotron U-150M of the Institute of Nuclear Physics. A self-supporting 27Al foil have been chosen as the objects of our investigation since it is the construction elements of a hybrid nuclear energy plant and experimental data on which are necessary for the development of ADS systems The double-differential cross sections of the reactions with light particles in exit channels were measured in the angular range 30-135o with angle increments of 15°.
Theoretical analysis of the obtained experimental results was performed within the framework of the TALYS calculation code. To describe the complete inclusive spectra of scattered particles, all possible mechanisms of nuclear reactions were taken into account. A satisfactory agreement between experimental and calculated values has been achieved. A distinction between direct nuclear reactions, pre-equilibrium decay and equilibrium emission at different incident protons energy for 27Al(p,x) reactions were established.
