3 weeks ago - The primary decay mode for isotopes of Pa lighter than (and including) the most stable isotope 231Pa is alpha decay, except for 228Pa to 230Pa, which primarily decay by electron capture to isotopes of thorium. The primary mode for the heavier isotopes is beta minus (β−) decay.

Nuclear levels of 228Th populated in the decay of 228Pa - Archive ouverte HAL
, — The decay of 228Pa to the levels of 228Th has been extensively studied by various techniques. Single spectra of γ-and K X-rays have been measured with Si(Li) and Ge(Li) detectors. A set of two Ge(Li) detectors has been used to study γ-y and γ-K X-ray coincidences.

Investigation of the 230Th(p,2n)229Pa Reaction as a Route to 225Ac
Nuclear data measurements were done for several relevant protactinium isotopes, including half-life measurements for 228Pa and 229Pa, and modern measurements of the major gamma-ray emissions from the decay of 231Pa. For many of these measurements, the error envelopes have been significantly ...

February 1, 2014 - The nucleus 228Pa was only reached with incoming deuterons. The results are compared with exciton-model predictions including compound-nucleus emission and fission competition. While for incoming deuterons these equilibration calculations give reasonable agreement with the data, the prequilibrium ...

Nuclear levels in 228Th populated in the decay of 228Pa (II) - The European Physical Journal A
The electron-capture decay of 228Pa to levels in 228Th was studied using mass-separated sources and a γ-ray detection system consisting of five Compton-suppressed Ge detectors. A total of 87 levels were observed up to an excitation energy of 2 MeV which are connected by approximately 500 γ-ray ...
