69. Pandemonium free data for reactor applications

Alejandro Algora (IFIC (CSIC-Univ. of Valencia))

Is this talk I will cover the systematic study of beta decays performed by our collaboration in relation to reactor applications. The main goal is to provide Pandemonium free decay data to improve decay heat and antineutrino spectrum calculations. Particular emphasis will be devoted to our recent beta spectrum shape experiments, that allow us to validate the corrections needed for the...

57. Study opportunities with the LOHENGRIN fission fragment separator

The recoil mass-separator LOHENGRIN at Institut Laue-Langevin (ILL) selects fission fragments produced by actinide targets in a thermal neutron flux of about 5x1014 n/cm2/s in an in-pile position of the high-flux reactor. The experimental study of nuclear fission and fission products is of particular interest for both fundamental and applied physics. The performance of the LOHENGRIN...

1. Multi-phonon gamma vibration study from AGATA+Gammasphere complimentary setup

Enhong Wang (Shandong University)

Rapid shape change occurs in neutron-rich nuclei in the A∼100 region. Some of the nuclei in this region also exhibits ellipsoidal shape oscillations, known as gamma vibrations and linked to triaxiality and gamma softness. Furthermore, the two-phonon gamma-vibrations also provide tests of Pauli principle. To study of the evolution of the shapes and level structure, the 104Nb was investigated...

13. Cluster radioactivity fission valleys along isotopic and isotonic chains of heavy and super-heavy nuclei

Michał Warda (Maria Curie-Skłodowska University, Lublin)

Most heavy and super-heavy nuclei decay through fission or alpha emission, but other decay modes can also be noticed. In the 1980s, an exotic decay of cluster radioactivity was observed in actinides [1, 2, 3]. A light nucleus, but heavier than an alpha particle, is emitted in this process. The heavy mass residue is a doubly magic $^{208}$Pb in all observed decays of this type.
