It has never been observed in the proton-induced nuclear reaction (p,n2), which is the goal of the proposed experiment we are planning to conduct for the first time, using enriched 100Mo as target nuclei. The proposed research concerns then the bound dineutron observation via 99mTc decay and the corresponding nuclear reaction might serve as an additional source for production of medically relevant 99mTc. With the same setup, we intend to develop a novel methodology for a hybrid production of 99mTc by simultaneous proton and proton-induced neutron irradiations of molybdenum samples, properly located within the target assembly in medical cyclotrons. Under this approach, the main issue is to realize a multi-layer sample with the proper thicknesses and a suitable target assembly to ensure an effective irradiation allowing for a maximum yield of tracer.
