72As, a powerful positron emitter for immunoimaging and receptor mapping: Study of the cyclotron production

The excitation functions for the 72 Ge( p,n ) 72 As and nat Ge( p,xn ) 72 As reactions were calculated by ALICE/91, ALICE/ASH, and TALYS-1.2 codes and compared to the existing data. Deposition of GeO 2 on a Cu substrate was carried out using two special sedimentation methods for the production of 72...

Summary:The excitation functions for the 72 Ge( p,n ) 72 As and nat Ge( p,xn ) 72 As reactions were calculated by ALICE/91, ALICE/ASH, and TALYS-1.2 codes and compared to the existing data. Deposition of GeO 2 on a Cu substrate was carried out using two special sedimentation methods for the production of 72 As, and a simple procedure for As separation was described. The targets were checked by SEM and thermal shock test. The optimal thicknesses of the target was substantiated, and theoretical calculation of the production yield was made for the 72 Ge( p,xn ) 72 As reaction.
