A new two-body interaction is derived for nuclei in a large part of the 0flp shell by fitting two-body matrix elements to 494 energy levels in A = 41-66 nuclei. For the shell-model basis a 4°Ca core and a model space consisting of 0~/2 ( lp3/20fs/2 lpl/2)m + 0~7~1 ( lp3/20f5/2 lpl/2) l+ra configurations was assumed. By varying 40 linear combinations of matrix elements and fixing those that are ...
We propose a new approach to calculate perturbatively the effects of a particular deformed Heisenberg algebra on an energy spectrum. We use this method to calculate the harmonic oscillator spectrum and find that the corrections are in agreement with a previous calculation. Then, we apply this approach to obtain the hydrogen atom spectrum and we find that splittings of degenerate energy levels a...
In this paper, a bi-level optimization problem is formulated to find the optimal strategy of energy retailer in integrated energy market using smart energy hub concept. In the upper level problem, the energy retailer determines the price of energy carriers and the purchase amount from the wholesale market aiming to maximize his own profit. The consumers decide on their purchase amount of energy...
Background & Aim: Energy is one of important debates in agriculture ecology and for this reason; the ratio of output and input energy in different agriculture ecosystems has been calculated. If one can reduce, input energy level into farms through the indices like poisons, fertilization, tractor energy and lab our force. In addition to the net income of the farmers, this issue would play a sign...
abstract this study investigates the teachers’ correction of students’ spoken errors of linguistic forms in efl classes, aiming at (a) examining the relationship between the learners’ proficiency level and the provision of corrective feedback types, (b) exploring the extent to which teachers’ use of different corrective feedback types is related to the immediate types of context in which err...
