Abstract

We investigated the natTi(d,x)48V reaction cross-sections by using a stacked-foil activation technique in combination with HPGe γ-ray spectrometry at the AVF cyclotron facility of the RIKEN RI Beam Factory, Wako, Japan. An overall good agreement is found between the measured data and the literature ones, whereas partial agreement is obtained with the theoretical data extracted from the TENDL-2011 library provided by the TALYS model calculations. Measured cross-sections of natTi(d,x)48V reactions find significance in monitoring of deuteron beam parameters from threshold to 50 MeV. Furthermore, IAEA recommended cross-sections of natTi(d,x)48V reaction has been verified here, and found a very good agreement. Additionally, measured cross-sections of the natTi(d,x)48V reactions find significance in various practical applications including nuclear medicine. [ABSTRACT FROM AUTHOR]

Abstract

The nuclear-physical properties of Ti (half-life 3.08 h, 85% β-decay, 15% electron capture, daughter isotope Sc) make it suitable for positron emission tomography. Ti can be produced at a small cyclotron in a high yield, 450 MBq μA h, using the Sc( p,n)Ti nuclear reaction on a natural scandium target. The excitation functions for the Sc( p,n)Ti reaction were calculated by ALICE/91, ALICE/ASH, and TALYS-1.2 codes and compared to the existing data. Deposition of ScO on a Cu substrate was carried out by two sedimentation methods for the production of Ti, and a simple method for radiochemical separation of radiotitanium was suggested. The targets were examined by SEM and subjected to thermal shock test. The optimal thicknesses of target was substantiated, and the production yield for the Sc( p,n)Ti reaction was calculated.

Abstract

Abstract: Independent and cumulative production cross-sections for the natTi(p,x)48V, 43,44m,44g,46,47,48Sc nuclear processes are reported here, for the energy region of 4–38MeV by using a stacked-foil activation technique. Measured data were critically compared with the earlier reported values, and also with the theoretical data from the TALYS and ALICE-IPPE codes. The measured natTi(p,x)48V reaction is important for charged particle beam monitoring purposes, whereas the 43,44,47Sc radionuclide have various practical applications in nuclear medicine.
