An antisymmetrized microscopic calculation of the optical potential for nucleon-40Ca elastic scattering is derived. RPA correlations taken into account in the one-particle mass operator are shown to bring a correction to the first-order real potential at low energies and to lead to an imaginary potential. Both are calculated for incident nucleon energies between 10 and 50 MeV. Their general properties are studied in great detail and, after comparison with empirical imaginary potentials, the reliability of such an approach is discussed according to the value of the incident energy. 相似文献

This paper pursues a twofold goal. First goal is to derive new results on generalized differentiation in variational analysis
focusing mainly on a broad class of intrinsically nondifferentiable marginal/value functions. Then the results established
in this direction are applied to deriving necessary optimality conditions for the optimistic version of bilevel programs,
which occupy a remarkable place in optimization theory and its various applications. We obtain new sets of optimality conditions
in both smooth and nonsmooth settings of finite-dimensional and infinite-dimensional spaces. 相似文献

The aim of the present paper is to introduce a metric locally convex topology on the space
of δ-psh functions in the Cegrell class
. We prove that with this topology
is a non-separable and non-reflexive Fréchet space. At the same time, we extend the Monge–Ampère operator from the class
to

Spatial periodic forcing of pattern-forming systems is an important, but lightly studied, method of controlling patterns. It can be used to control the amplitude and wave number of one-dimensional periodic patterns, to stabilize unstable patterns, and to induce them below instability onset. We show that, although in one spatial dimension the forcing acts to reinforce the patterns, in two dimensions it acts to destabilize or displace them by inducing two-dimensional rectangular and oblique patterns. 相似文献
