The SHELS velocity filter originated upon reconstruction of the VASSILISSA electrostatic separator used for investigations of heavy nuclei produced in complete fusion reactions. The goals of this modernization were to increase the transmission of products of asymmetric reactions and to extend the region of reactions to be investigated up to symmetric combinations. The first tests of the set-up were performed with the beams of accelerated 22 Ne, 40 Ar, 48 Ca, and 50 Ti ions. [ABSTRACT FROM AUTHOR]

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.

Abstract: Results are presented from a one-neutron knockout reaction at relativistic energies on 56Ti using the GSI FRS as a two-stage magnetic spectrometer and the Miniball array for gamma-ray detection. Inclusive and exclusive longitudinal momentum distributions and cross-sections were measured enabling the determination of the orbital angular momentum of the populated states. First-time observation of the 955(6) keV -hole state in 55Ti is reported. The measured data for the first time proves that the ground state of 55Ti is a state, in agreement with shell-model calculations using the GXPF1A interaction that predict a sizable gap in 54Ca.

Abstract: The excitation functions of proton induced reactions on Sc targets (100% 45Sc), leading to the formation isotopes 43K, 43Sc, 44mSc, 44gSc and 44Ti were studied by the stacked foil activation technique up to 37MeV. High-resolution gamma-spectrometry measurements were performed on an HPGe detector in order to determine the activity of the irradiated Sc2O3 pellets and Ti monitor foils. The reaction cross-sections were measured from their respective thresholds up to E p =36.4MeV and were compared with previous values reported in literature. Possible batch yields and optimal irradiation parameters for generator 44Ti –44gSc in high current accelerators are discussed. [Copyright &y& Elsevier]
