“…In recent years, as a result of further development of nuclear models and availability of advanced computer codes, it has become possible to calculate many of the nuclear reaction data and possibly predict some gaps in the literature. Proton induced reactions on 76 Se, 77 Se, 78 Se, 80 Se and nat Se leading to the formation of bromine radioisotopes were experimentally investigated in recent years [16,17] and the cross section data were validated by the computer code ALICE-IPPE [16]. We critically surveyed all the nuclear reactions used for the no-carrier-added production of 77 Br and 77 Kr, and compared the concordant set of cross section data with the results of nuclear model calculations.…”

“…The incident energy on the sample was verified using a Cu foil as monitor [47] and was found to be 16.5 ± 0.2 MeV. This energy is not enough for producing a large amount of 77 Br activity due to low cross section for protons on nat Se [24]. The results are shown in Figure 6.…”

Selenium compounds of Zn, Sn and Cu were prepared using a conventional sintering method and the phase composition of each compound was investigated using X-ray diffraction. The compounds prepared were tested under variable irradiation and separation conditions for 76,77 Br production. The activity of 77 Br was measured as a function of proton beam current within the range 2-15 μA and the thermal stability of the irradiated compound was investigated. The results showed that the compounds ZnSe and Cu 2 Se are thermally more stable in comparison to the SnSe. The effects of several factors, such as temperature, gas flow rate and separation time, were studied to obtain the maximum separation yield of radiobromine by the dry distillation method. The data showed that the compound Cu 2 Se is the most suitable target for proton irradiation to produce 76,77 Br at energies up to 20 MeV. A simplified method was used to prepare also CuSe, which was tested in irradiations with intermediate energy protons of beam currents up to 10 μA. The data of a typical production run using 17 MeV protons and the Cu 2 Se target are reported.

“…As an example, we consider the data for the production of 76 Br [59,60]. An evaluation has been done [63] and from the recommended cross sections the yields of 76 Br via three reactions, namely 76 Se( p, n) 76 Br, 77 Br( p, 2n) 76 Br and 78 Se( p, 3n) 76 Br, were calculated.…”

Medical radionuclide / Optimisation of production route / Nuclear reaction cross section / Standardisation of data / Alternative routes for production of 99m Tc and 68 Ga / Non-standard positron emitter / Novel therapeutic radionuclide Summary. Nuclear reaction cross section data are of great significance in optimisation of production routes of radionuclides. This article deals with some newer aspects of data research related to production of both standard and novel radionuclides. The recent work to standardise the known data is discussed and new measurements with regard to further optimisation of production routes of some commonly used radionuclides are mentioned. Attempts to increase the specific activity of some reactor-produced radionuclides through the use of charged-particle induced reactions are outlined. The jeopardy in the supply of 99m Tc via a fission-produced 99 Mo/ 99m Tc generator is considered and its possible direct production at a cyclotron is briefly discussed. Regarding the novel radionuclides, development work is presently focussed on non-standard positron emitters for diagnosis and on low-range highly ionising radiation emitters for internal radiotherapy. Recent nuclear reaction cross section measurements related to the production of the two types of radionuclides are briefly reviewed and some anticipated trends in nuclear data research are considered.
