Recoil-$$alpha$$-fission and recoil-$$alpha$$-$$alpha$$-fission events observed in the reaction $$^{48}$$Ca + $$^{243}$$Am

Alpha-decay chains observed in the element-115 production reactions of $$^{48}$$Ca + $$^{243}$$Am were investigated using a new data set consisting of our recently reported data obtained at GSI and previously reported ones at Dubna and LBNL. Short decay chains of recoil-$$alpha$$-($$alpha$$)-fission type, fourteen of which were observed, and some of which were interpreted as the 2-neutron evaporation products $$^{289}$$Mc, have been reassigned. It is plausible that most of them were assigned to the 3-neutron evaporation products $$^{288}$$Mc whose decay chain would on the way have branches of EC decays followed by fission.

Reliability assessment of high energy particle induced radioactivity calculation code DCHAIN-SP 2001 by analysis of integral activation experiments with 14MeV neutrons

Reliability assessment for the High Energy Particle Induced Radioactivity Calculation Code DCHAIN-SP 2001 was carried out through analysis of integral activation experiments with 14-MeV neutrons. The following three series of experiments conducted at the D-T neutron source facility, FNS, in JAERI were employed: (1) the decay gamma-ray measurement experiment for fusion reactor materials, (2) the decay heat measurement experiment for 32 fusion reactor materials, and (3) the integral activation experiment on mercury.As a result, it was found that the calculations with DCHAIN-SP 2001 predicted the experimental data for (1)$$sim$$(3) approximately within 30%, 20% and 20%, respectively. It was concluded that the activation cross section data below 20 MeV and the associated decay data as well as the calculation algorithm for solving the Beteman equation that was the master equation of DCHAIN-SP were adequate.

Development of the radioactivedecay Python package for radioactive decay calculations

Malins, A.

no journal, , 

The inventories of radioactive nuclides present at nuclear power plants, research institutions, hospitals, in the environment, etc., change continuously due to radioactive decay. radioactive decay is an easy-to-use Python package that can calculate the changes in activities of radionuclides due to radioactive decay to high precision. The source code is published via GitHub and the Python Package Index (PyPI). This talk will explain the features and the development process of the code.
