چکیده
The reaction 45Sc(n, P)45Ca has been studied at an energy of 198 MeV with energy resolution of about 1 MeV. Measurements were carried out at nominal angles 0°, 3°, 6®, 9®, 12°, 15°, 18" and spectra obtained up to -40 MeV excitation energy in 45Ca . Significant Gamow-Teller strength is observed at an excitation energy of about 7 MeV, somewhat higher than predicted by shell-model calculations . The strength observed is in agreement with calculations using gA/g .̀ =1 . The spindipole giant resonance is seen with centroid at about 15 MeV excitation and total cross section of 25 mb/sr at an angle of 6° . E NUCLEAR REACTION 45Sc(n, Ca, E =198 MeV; measured o,(E,, 0). Deduced GT strength, spin-dipole o, Shell model comparison.

Fission of 238U nuclei was performed by 45-69 MeV protons at the Cyclotron and Radioisotope Center of Tohoku University in Japan. The fission products originated in the reaction were identified by using gamma spectroscopy. The experimental data show that the charge distribution of isobar fission products follows a Gaussian distribution with a standard deviation independent of the selected mass...

Thin targets of 238U were bombarded with 45, 55, 65 and 69 MeV protons at the Cyclotron and Radioisotope Center (CYRIC) of Tohoku University in Japan. Gamma rays emitted from the fission products were recorded and analyzed by using gamma spectroscopy. Then, the cross sections for the formation of fission products, fragment mass distributions, and total fission cross sections were measured. Spec...

Background & Aims: Copper-61 (61Cu) is a radioisotope with a half-life of 3.33 hours which decays to nickel-61 isotope byβ+ emission (61%) or electron capture (39%). This radioisotope can be used in the evaluation of the blood supply of the heart and low-oxygen cancer tissues imaging with PET. 61Cu is mainly produced by bombarding zinc (Zn), nickel (Ni) and cobalt (Co) targets in medium cyclot...

The 12C(12C,14O) two-proton pick-up reaction has been measured at 211.4 MeV incident energy to study the structure of states of 10Be up to excitation energies of 12 MeV. The measured partial angular distributions show pronounced oscillatory shapes, which were described by coupled-reaction-channels calculations. Spin-parity assignments could be derived from these characteristic shapes and two de...
