Protactinium neutron-induced fission up to 200 MeV

open access: yesEPJ Web of Conferences, 2010
The theoretical evaluation of 230-233Pa(n,F) cross sections is based on direct data, 230-234Pa fission probabilities and ratios of fission probabilities in first-chance and emissive fission domains, surrogate for neutroninduced fission.

influence of gold mining on radioactivity of mining sites soil in Tanzania

open access: yesEQA, 2022
The activity of 226Ra, 232Th and 40K in soil samples were measured by gamma spectrometry using high-purity germanium detector. The study involved 40 samples from four divisions: 10 samples each were drawn from the control area (CTR), washing area 1 (W1),

Dynamical approach to heavy ion-induced fission

open access: yesEPJ Web of Conferences, 2015
Deep inelastic collisions (DICs) can compete strongly with fusion in collisions of heavy nuclei. However, standard coupled-channels calculations do not take DIC processes into account.
