The Importance-Truncated NCSM (IT-NCSM) formulated on arguments of multi-configurational perturbation theory selects a small set of basis states from the initially large basis space in which the Hamiltonian is diagonalized. Previous IT-NCSM calculations have proven reliable, however, there has been no thorough investigation of the inherent error in the truncated IT-NCSM calculations. This thesis provides a detailed study of IT-NCSM calculations and compares them to full NCSM calculations to judge the accuracy of IT-NCSM in heavier nuclei. When IT-NCSM calculations are performed, one often needs to extrapolate the ground-state energy from the finite basis (or model) spaces to the full NCSM model space. In this thesis a careful investigation of the extrapolation procedures was performed. On a related note, extrapolations in the NCSM are commonplace, but up to recently did not have the ultraviolet (UV) or infrared (IR) physics under control. This work additionally presents a method that maps the NCSM parameters into an effective-field theory inspired framework, in which the UV and IR physics are treated appropriately. The NCSM is well-suited to describe bound-state properties of nuclei, but is not well-adapted to describe loosely bound systems, such as the exotic nuclei near the neutron drip line. With the inclusion of the Resonating Group Method (RGM), the NCSM / RGM can provide a first-principles description of exotic nuclei and the first extension of the NCSM. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aElementary particles (Physics) 606 $aQuantum field theory 606 $aNuclear physics 606 $aHeavy ions 606 $aString theory 606 $aElementary Particles, Quantum Field Theory$3https://scigraph.springernature.com/ontologies/product-market-codes/P23029 606 $aNuclear Physics, Heavy Ions, Hadrons$3https://scigraph.springernature.com/ontologies/product-market-codes/P23010 606 $aQuantum Field Theories, String Theory$3https://scigraph.springernature.com/ontologies/product-market-codes/P19048 615 0$aElementary particles (Physics). 615 0$aQuantum field theory. 615 0$aNuclear physics. 615 0$aHeavy ions. 615 0$aString theory. 615 14$aElementary Particles, Quantum Field Theory. 615 24$aNuclear Physics, Heavy Ions, Hadrons. 615 24$aQuantum Field Theories, String Theory. 676 $a539.743 700 $aKruse$b Michael Karl Gerhard$4aut$4http://id.loc.gov/vocabulary/relators/aut$01424554 906 $aBOOK 912 $a9910739432803321 996 $aExtensions to the No-Core Shell Model$93553829 997 $aUNINA
