Abstract It is shown that the Schrödinger equation for sum of potential a square well and Coulomb uniformly charged sphere admits an analytical solution arbitrary values orbital angular momentum. An explicit form this has been found. Using obtained solution, influence interaction both point distributed nuclear charges on asymptotic normalization coefficients various systems investigated. taking...

In an emulsion-counter hybrid experiment performed at J-PARC, a $\Xi^-$ absorption event was observed which decayed into twin single-$\Lambda$ hypernuclei. Kinematic calculations enabled unique identification of the reaction process as $\Xi^{-} + ^{14}$N$\ \rightarrow\ ^{10}_\Lambda$Be $^5_\Lambda$He. For binding energy $\Xi^{-}$ hyperon in $\Xi^-$-$^{14}$N system value $1.27 \pm 0.21$ MeV dedu...

The binding energy of nuclear matter including exchange and pionic effects is calculated in a quark-meson coupling model with massive constituent quarks. As in the case with elementary nucleons in QHD, exchange effects are repulsive. However, the coupling of the mesons directly to the quarks in the nucleons introduces a new effect on the exchange energies that provides an extra repulsive contri...

The 3C protein is a master regulator of the picornaviral infection cycle, responsible for both cleaving viral and host proteins, and interacting with genomic RNA replication elements. Here we use nuclear magnetic resonance spectroscopy and molecular dynamics simulations to show that 3C is conformationally dynamic across multiple timescales. Binding of peptide and RNA lead to structural dynamics...

This paper is designed to examine the binding behavior of Coumarin with bovine -casein (βCN) through fluorescence spectroscopy and molecular modeling techniques. The data analysis on fluorescence titration experiments at various temperatures represents the enthalpy driven nature for the formation of Coumarin–βCN complex and the prevailed role of hydrogen bonds and van der Waals interactions in...

The relative stiffness of naked DNA is evident from measured values of longitudinal persistence length (approximately 150 bp) and torsional persistence length (approximately 180 bp). These parameters predict that certain arrangements of eukaryotic transcription activator proteins in gene promoters should be much more effective than others in fostering protein-protein interactions with the basal...

RNA is commonly believed to undergo a number of sequential folding steps before reaching its functional fold, i.e., the global minimum in the free energy landscape. However, there is accumulating evidence that several functional conformations are often in coexistence, corresponding to multiple (local) minima in the folding landscape. Here we use the 5'-exon-intron recognition duplex of a self-s...

The statistical fluctuations of the ground–state energy and of the binding energy of nuclei are investigated using both perturbation theory and supersymmetry. The fluctuations are induced by the experimentally observed stochastic behavior of levels in the vicinity of neutron threshold. The results are compared with a recent analysis of binding–energy fluctuations by Bohigas and Leboeuf, and wit...

the theoretical calculation of the energies of projectile like fragments (plfs) using the heavy-ion reactions between 76ge and 198pt are reported in this article. the incident beam energy was 635 mev. the calculated values of plfs are compared with the previous experimental results and it is shown that the theoretical calculations of plfs are consistent with the experimental values. the elastic...
