WebMay 7, 2024 · Foraminifera shells are well known archives for paleoceanography and paleoclimate reconstructions. In addition to the use of foraminifera for biostratigraphy and paleoecology (e.g. CLIMAP project, 1976;Crowley, 2000), stable isotopes (δ 18 O and δ 13 C), trace elements and their isotopes (Cd/Ca, Mg/Ca, U/Ca, δ 11 B, and more) are … WebThe intrashell quartet states are obtained by exciting two protons and two neutrons from the highest occupied orbital to the lowest unoccupied orbital of the lowest Hartree-Fock solutions for some even-even (N=Z) nuclei in the ds and fp shells. These intrinsic quartet states are found to be very high in energy. The states with good angular momenta are …
