New calculations of cyclotron production cross sections of some positron emitting radioisotopes in proton induced reactions

In this study, new calculations on the excitation functions of ¹³C(p,n)¹³N, ¹⁴N(p,a)¹¹C, ¹⁵N(p,n)¹⁵O, ¹⁶O(p,a)¹³N, ¹⁸O(p,n)¹⁸F, ⁶²Ni(p,n)⁶²Cu, ⁶⁸Zn(p,n)⁶⁸Ga and ⁷²Ge(p,n)⁷² As reactions have been carried out in the 5–40 MeV incident proton energy range. In these calculations, the pre-equilibrium and equilibrium effects have been investigated. The pre-equilibrium calculations involve hybrid model, geometry dependent hybrid model, the cascade exciton model and full exciton model. Equilibrium effects were calculated according to Weisskopf-Ewing model. The calculated results have been compared with experimental data taken from literature.
