Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

An advanced pairing correction for an existing formula of particle-hole state densities, needed in calculations of cross sections with the precompound nuclear reaction theory, is examined. The Pauli correction is derived to be consistent with this pairing correction. The accuracy of the pairing correction plus the Pauli correction is shown to be sufficient for applied calculations. Numerical solutions of the pairing equations, needed for generating the corrections, have been carried out. The relevant numerical results are presented as simple functions of the excitation energy and the exciton number. A relationship between the pairing correction for particle-hole state densities and the pairing correction for the total state densities in the closed-form formulation is developed. Utilization of the existing level-density parameters and data for deducing parameters for the particle-hole state densities are shown.
