Calculation of exciton densities in the shell-model Monte Carlo method
نویسندگان
چکیده
We develop a shell-model Monte Carlo method to calculate densities of states with varying exciton ~particlehole! number. We then apply this method to the doubly closed-shell nucleus Ca in a full 0s-1d-0 f -1p shell-model space and compare our results to those found using approximate analytic expressions for the partial densities. We find that the effective one-body level density is reduced by approximately 22% when a residual two-body interaction is included in the shell-model calculation. @S0556-2813~99!04010-8#

We develop a shell-model Monte Carlo (SMMC) method to calculate densities of states with varying exciton (particle-hole) number. We then apply this method to the doubly closed-shell nucleus 40 Ca in a full 0s-1d-0f-1p shell-model space and compare our results to those found using approximate analytic expressions for the partial densities. We find that the effective one-body level density is red...
متن کاملStatistical Properties of Nuclei by the Shell Model Monte Carlo Method
We use quantum Monte Carlo methods in the framework of the interacting nuclear shell model to calculate the statistical properties of nuclei at finite temperature and/or excitation energies. With this approach we can carry out realistic calculations in much larger configuration spaces than are possible by conventional methods. A major application of the methods has been the microscopic calculat...
متن کاملParticle-Number Reprojection in the Shell Model Monte Carlo Method: Application to Nuclear Level Densities
We introduce a particle-number reprojection method in the shell model Monte Carlo that enables the calculation of observables for a series of nuclei using a Monte Carlo sampling for a single nucleus. The method is used to calculate nuclear level densities in the complete (pf + g9/2)-shell using a good-sign Hamiltonian. Level densities of odd-A and odd-odd nuclei are reliably extracted despite a...
متن کاملMonte Carlo calculation of shielding properties of newly developed heavy concretes for megavoltage photon beam spectra used in radiation therapy
Introduction: Globally, the need for radiotherapy as a part of cancer management increases every year. Thus, the shielding for megavoltage radiotherapy rooms is of great importance. Materials and Methods: In the present study, 14 types of developed high-density concrete with densities ranging from 2.45 to 5.11 were simulated by using Monte Carlo method. The linear attenuation coefficient and t...
متن کاملMicroscopic Nuclear Level Densities from Fe to Ge by the Shell Model Monte Carlo Method
We calculate microscopically total and parity-projected level densities for β-stable even-even nuclei between Fe and Ge, using the shell model Monte Carlo methods in the complete (pf +0g9/2)-shell. A single-particle level density parameter a and backshift parameter ∆ are extracted by fitting the calculated densities to a backshifted Bethe formula, and their systematics are studied across the re...
