(α, xn) Reactions on Natural Erbium

Production cross sections of ytterbium and thulium radioisotopes in alpha-induced nuclear reactions on natural erbium

“…The results are displayed in Figs. 2-9 with the previous experimental studies (Archenti et al, 1985;Homma et al, 1980;Király et al, 2008;Sonzogni et al, 1992) and the TENDL-2017 data (Koning et al, 2019). The production yield of 169 Yb deduced from the measured cross sections is shown in Fig.…”

“…The derived excitation function was shown in Fig. 3 with the experimental data studied earlier (Archenti et al, 1985;Sonzogni et al, 1992) and the TENDL-2017 data (Koning et al, 2019). The two previous experimental data are lower than our data.…”

“…2. The results are compared with the previous studies (Archenti et al, 1985;Homma et al, 1980;Király et al, 2008;Sonzogni et al, 1992) and the TENDL-2017 data (Koning et al, 2019). Both data of Király et al (2008) and TENDL-2017 have nearly the same peak position as ours at around 35 MeV while the amplitudes are different.…”

“…In this paper, we focused on the alpha-induced reactions on nat Er ( 162 Er: 0.139%, 164 Er: 1.601%, 166 Er: 33.503%, 167 Er: 22.869%, 168 Er: 26.978%, 170 Er: 14.910%). Four previous studies of the nat Er(α,x) 169 Yb reaction (Archenti et al, 1985;Homma et al, 1980;Király et al, 2008;Sonzogni et al, 1992) could be found in the EXFOR library (Otuka et al, 2014). However, the experimental data published earlier are rather inconsistent.…”

Excitation functions of alpha-induced nuclear reactions on natural erbium and natural ytterbium targets

“…Two authors reported data measured on nat Er target. Data of Archenti et al [11] are very scattered and therefore less reliable. The points of Sonzogni et al [12] follow a curve that is similar to ours but are a factor of 3 lower.…”
