The [Formula: see text]Tc isomer was produced using the [Formula: see text] reaction on highly enriched [Formula: see text]Mo samples. The Thick Target Yields were determined in the energy range from 16 MeV to 26 MeV and compared with the values calculated using the most recent cross-section recommendations from the literature. The generated impurities were also determined. It was shown that for 99.815 ± 0.010% enriched samples, only reactions induced on [Formula: see text]Mo are of importance. The ratio of the number of atoms of [Formula: see text]Tc to all produced Tc nuclei was studied as a function of irradiation time and bombarding energy.

Isomer ratios of 90Y and 91Y formed in the fission of 235U and 238U induced by protons of energies 20–85 MeV have been determined. For both 90Y and 91Y the isomer ratios are always higher in 235U fission than in 238U fission. Isomer ratios of 90Y in 238U fission and those of 91Y in 235U and 238U fission remain almost constant in the energy range of 20–85 MeV, whereas those of 90Y in 235U fission increase with increasing bombarding energy. A theoretical calculation of these ratios indicates that the primary fragments leading to the formation of these isomers possess [Formula: see text] units of angular momentum.

The 19F(p,α0)16O and 19F(p,απ)16O reactions can be fruitfully exploited to probe natural parity states above the proton emission threshold in the compound 20Ne nucleus. However, despite the relatively large number of data sets published in the literature, it is still not possible to draw a fully unambiguous picture of the spectroscopy of 20Ne, especially close to the proton emission threshold. To contribute to clarify these aspects, we have collected and reviewed all existing data sets of the 19F(p,α0)16O and 19F(p,απ)16O reactions to perform, for the first time, a comprehensive R-matrix fit including both reactions in the bombarding energy range Ep = 0:2–10 MeV. Our analysis clarifies several ambiguities present in the literature and affecting the spectroscopy of 20Ne and clearly demonstrates the importance of the 19F(p,απ) reaction to better constraint the spectroscopy parameters of the fit.

An analysis has been made of the isomer ratio, σm/((σm + σg) for 134Cs isomers formed in the fission of 237Np by protons of energies 20–85 MeV. Compound nucleus formation was assumed up to a bombarding energy of 50 MeV, with direct interaction as the mechanism at higher energies. Values of the root-mean-square angular momentum of [Formula: see text] at 20 MeV and [Formula: see text] at 60–85 MeV bombarding energy agree with the experimental results. The results are consistent with the hypothesis that angular momentum is generated in the fission process.
