Level studies of 93Mo via 93Nb(p, nγ)93Mo reaction and density of discrete levels in 93Mo

The excited states of 93Mo have been investigated via the 93Nb(P,nγ)93Mo reaction with proton beam energies of 2.5-4.3 MeV. The parameters of the nuclear level density formula were determined from the extensive and complete level scheme of 93Mo. The Bethe formula for the back-shifted Fermi gas model and the constant temperature model are compared with experimental level densities

Simulation of vanadium-48 production using MCNPX code

Vanadium-48 was produced through the irradiation of the natural titanium target via the natTi(p, xn)48V reaction. The titanium target was irradiated at 1 mA current and by a 21 MeV proton beam for 4 hours. In this paper, the activity of 48V, 43Sc, and 46Sc radionuclides and the efficacy of the 47Ti(p, g), 48Ti(p, n), and 49Ti(p, 2n) channel reactions to form 48V radionuclide were determined using MCNPX code. Furthermore, the experimental activity of 48V was compared with the estimated value for the thick target yield produced in the irradiation time according to MCNPX code. Good agreement between production yield of the 48V and the simulation yield was observed. In conclusion, MCNPX code can be used for the estimation of the production yield

Cyclotron production of ^94mTc via ⁹⁴Mo (p, n) ^94mTc reaction

7-1094mTc is an important positron-emitting radionuclide for Positron Emission Tomography (PET). 94mTc has been produced using the 94Mo (p, n) 94mTc nuclear reaction by Cyclotron (Cyclone-30, IBA, Belgium) at the Agricultural, Medical and Industrial Research School (AMIRS). Deposition of MoO3 on Cu substrate was carried out via two special sedimentation methods for the production of 94mTc. The natural molybdenum target has been irradiated with a 15 MeV proton beam and the production yield is measured as 341.8±47.9 MBq/μAh. The comparison of present experimental result with calculation data (TALYS-1.0 code result) is shown that the pre-equilibrium particle emission of 94mTc is described using the two-component Exciton model. </span
