Excitation Function Measurements
of Alpha-Induced Reaction on Natural
Copper and Titanium Up To 46 MeV
Hiroshi Yashima, Masayuki Hagiwara, Toshiya Sanami, and Shunsuke Yonai
1 Introduction
The activation cross section data are required for isotope production, activation
detector, residual activity assessment and so on, although experimental data are very
scarce for heavy ions. We, therefore, irradiated 46.4 MeV alpha beam onto a target
to obtain experimental data of residual radioactivities for low energy heavy ions.
2 Experiment and Analysis
The Irradiation experiment was performed at cyclotron facility (NIRS-930),
National Institutes for Quantum and Radiological Science and Technology. A
schematic view of the experimental set-up is shown in Fig. 1. The target was
composed of a stack of 15 mm × 15 mm × 0.01 mm natural Cu and Ti foils,
and total thickness of target was thicker than the range of projectile alpha beams.
The beam current on the target was recorded with a current integrator, connected
to a multichannel scaler to monitor the fluctuations of the alpha beam. The two
target irradiations were performed for a shorter irradiation time and a longer
