Production cross sections of 153,145Sm via alpha-particle-induced reactions on natNd were measured up to 23 MeV. The stacked-foil activation technique and high-resolution gamma-ray spectrometry were adopted for the measurement. The obtained cross sections were compared with the literature data and the TENDL-2019 and TENDL-2021 values. Physical thick target yields of the two radionuclides were derived from the measured cross sections.

Excitation functions of alpha-particle induced reactions on natNd up to 50 MeV were measured at the RIKEN AVF cyclotron. To derive cross sections activation method, stacked target technique and gamma-ray spectrometry were adopted. Formations of 153,145Sm, 151,150,149,148m,148g,144,143Pm, and 149,147Nd were investigated. The results were compared with the previous experimental data and the TENDL-2019 data. Discrepancies among most of them were found.

Activation cross sections of the 169Tm(p,n)169Yb reaction were measured up to 18 MeV. The stacked-foil activation technique and the high-resolution gamma-ray spectrometry were adopted to derive the cross sections. The result is compared with previous experimental data and theoretical model calculation. Physical yield of 169Yb is derived from the measured cross sections and compared with those from other production routes.

Activation cross sections of the deuteron-induced reactions on 89Y were measured up to 24 MeV deuteron energy. The experiment was performed at the RIKEN AVF cyclotron. Excitation functions of the reactions 89Y(d,x)88,89Zr, 88,90mY, 87mSr were obtained by using the stacked-foil activation method and gamma-ray spectrometry. The results were compared with previous experimental data and the prediction of the TALYS nuclear reaction model code adopted from TENDL-2017 library. Physical thick target yield of 89Zr was derived from the measured cross sections.

Activation cross sections of alpha-induced reactions on natural erbium were measured using a 50.9-MeV alpha-beam at the RIKEN AVF cyclotron. Well-established methods for the measurements, the stacked-foil activation technique and gamma-ray spectrometry, were used. Production cross sections of 166,169Yb and 165,166,167,168,170,173Tm were determined. This is the first measurement of the cross sections of 166,170Tm. The integral yield of the medical radionuclide 169Yb was derived from the measured excitation function.

The production of Sn-117m by charged-particle induced reactions is an interesting topic for medical application. Production cross sections of alpha-induced reactions on In-nat for Sn-117m up to 50 MeV were measured using the stacked foil technique and activation method. The integral yield of Sn-117m was estimated using the measured cross sections. The results were compared with experimental data investigated earlier and theoretical calculation. Measured cross sections for Sn-113 and Sb-116m,Sb-117,Sb-118m isotopes were also presented.

The production cross sections of Ge-68,Ge-69 and Ga-66,Ga-67 by alpha-induced reactions on Zn-nat have been measured using the stacked-foil activation method and off-line gamma-ray spectrometry from their threshold energies to 50.7 MeV. The derived cross sections were compared with the previous experimental data and the calculated values in the TENLD-2017 library. Our result shows a slightly larger amplitude than the previous data at the peak, though the peak energy is consistent with them.

Activation cross sections for deuteron-induced reactions on natural palladium were measured up to 24 MeV using the stacked-foil method and the high resolution gamma-ray spectroscopy. The production cross sections of 103Ag, the parent of a medical radioactive isotope 103Pd, were obtained. We found that our result is in good agreement with the previous data up to 20.3 MeV, and obtained new data at higher energies. In addition, the production cross sections of 104g+mAg, 105Ag, 106mAg, 110mAg and 111Ag were presented.
