Total and Parity-Projected Level Densities of Iron-Region Nuclei in the Auxiliary Fields Monte Carlo Shell Model
We use the auxiliary-fields Monte Carlo method for the shell model in the complete (pf + 0g9/2)-shell to calculate level densities. We introduce parity projection techniques which enable us to calculate the parity dependence of the level density. Results are presented for 56Fe, where the calculated total level density is found to be in remarkable agreement with the experimental level density. T...
متن کاملTotal and Parity-Projected Level Densities of Iron-Region Nuclei by the Shell Model Monte Carlo Method
Total and parity-projected level densities of iron-region nuclei are calculated microscopically by using Monte Carlo methods for the nuclear shell model in the complete (pf + 0g9/2)-shell. The calculated total level density is found to be in good agreement with the experimental level density. The Monte Carlo calculations offer a significant improvement over the thermal Hartree-Fock approximatio...
متن کاملShell-model Monte Carlo studies of fp-shell nuclei.
We study the gross properties of even-even and N = Z nuclei with A = 48 64 using shell-model Monte Carlo methods. Our calculations account for all 0 h! con gurations in the fp-shell and employ the modi ed Kuo-Brown interaction KB3. We nd good agreement with data for masses and total B(E2) strengths, the latter employing e ective charges ep = 1:35e and en = 0:35e. The calculated total Gamow-Tell...
متن کاملParity Dependent Shell Model Level Densities for Nuclear Astrophysics
Recently, we developed a methodology [1-4] of calculating the spin and parity dependent shell model nuclear level density, which is a very useful ingredient in the Huaser-Feshbach theory for calculating reaction rates for nuclear astrophysics[5]. We developed new techniques based on nuclear statistical spectroscopy [6] to calculate the spin and parity projected moments of the nuclear shell mode...
متن کاملShell model Monte Carlo investigation of rare earth nuclei
We utilize the shell model Monte Carlo method to study the structure of rare earth nuclei. This work demonstrates the first systematic full oscillator shell with intruder calculations in such heavy nuclei. Exact solutions of a pairing plus quadrupole Hamiltonian are compared with the static path approximation in several dysprosium isotopes from A5152 to 162, including the odd mass A5153. Some c...
