(Skyrme) Bohr Hamiltonian Database Author: David Muir Email: davidmuir.physics@gmail.com Last updated: 23/10/2021 The following results database is composed of (Skyrme) Bohr Hamiltonian (BH) calculations from the PhD work of David Muir at the University of York 2021. The thesis and any associated publication to this work elaborates on the specific details of the calculations themselves. This work builds on previous works (referenced in the PhD thesis) and was done in collaboration with: Leszek Prochniak Alessandro Pastore Jacek Dobaczewski This database is designed to grow over time with the addition of more nuclei, more functionals and further analysis. Any feedback or proposed additions/corrections are most welcome (see publications or above for contact details). CURRENT DATABASE STRUCTURE The folder "BH_Nuclear_Chain_Analysis" contains a list of isotopic chains named by their chemical element symbol. Inside each folder there is a folder/are folders named as a density functional which was used to microscopically calculate the mass parameters entering in the Bohr Hamiltonian. Inside this folder there is a name noting the chemical element symbol and the density functional used for calculation e.g. "Ba_UNEDF0_Isotopic_Chain_Analysis". Within this folder are the outputs for the BH calculations of this isotopic chain. Any missing nuclei failed to converge to the required level and are a work in progress. The current (example) outputs are: Ba_UNEDF0_Global_Data_Files: Contains numerical results for nuclear states/spectra and low-lying BE2 transitions. Energy States/Spectra "Ba_Isotopic_Chain_UNEDF0_2_1_States.txt" : Contains the numerical data for the 2_1 state. "Ba_Isotopic_Chain_UNEDF0_2_1_States_TV.txt": Contains the numerical data for the 2_1 state by where the mass parameters have been scaled (by a factor of 1.3) to account for the missing Thouless-Valatin terms neglected by the current calculations. Both files have the structure as follows (3 columns): N Z Energy State "Ba_Isotopic_Chain_UNEDF0_BE2_4_1_to_2_1.txt": Contains the BE2 transition probabilities in W.u. for the 4_1 -> 2_1 transition. "Ba_Isotopic_Chain_UNEDF0_BE2_4_1_to_2_1_TV.txt": Contains the BE2 transition probabilities in W.u. for the 4_1 -> 2_1 transition again where the mass parameters have been scaled. Both files have the structure as follows (3 columns): N Z BE2 (W.u.) Ba_UNEDF0_PES: Contains the potential energy surfaces (PES) for the fully triaxial calculations as pdf files e.g. "Ba120_UNEDF0_16_Shells.pdf". A pdf document entitled e.g. "Ba_Bohr_Hamiltonian_Analysis.pdf" containing graphs of the energy spectra and PES for the isotopic chain in one summary document. Additionally, the graphs found in "Ba_Bohr_Hamiltonian_Analysis.pdf" are also available in this folder as standalone pdfs. PLEASE REFERENCE THIS WORK IN ALL FUTURE WORKS. THANK YOU.
