چکیده
funktionen selbst kann also allenfalls darin gesehen werden, daß die ersten beiden Koeffizienten in ( 1) ungefähr gleich dem arithmetischen Mittel der Ko effizienten in Tab. 3 sind. Vergleicht man dagegen bei den nach den beiden Methoden bestimmten Zustandsfunktionen die Elek tronendichte im 3-dimensionalen Raum, so findet man nur geringfügige Unterschiede. Als Beleg dafür ist in der Abb. 6 die Elektronendichte längs der Kernverbindungslinie gezeichnet, und zwar in ge strichelten Kurven für die Ransil-Funktion, in aus gezogenen Kurven für und nur durch einige Kreuze angedeutet für • Obgleich nun die Abbil dungen für das Dichte„plateau“ um die Molekül mitte deutlich einen höheren Wert bei der RansilFunktion zeigen, ist doch die Folgerung zu ziehen, daß die drei Funktionen V ’ R a n s i l , Y’a , iph in diesem Gebiet zu fast gleicher Dichte führen würden, wenn die Kernabstände gleich wären; denn bei der Ver kürzung des Abstands von 5,224 und 5,051 ist na türlich eine Erhöhung der Dichte um den Faktor (5,224/ 5,051)3, d .h . um 11% zu erwarten. Nur der über diese 11% hinausgehende Unterschied zwi schen den Dichten ist also als echter Unterschied an zusehen. Er ist sehr klein und rührt her von der Gleichheit der Koeffizienten für homöopolare und ionische Anteile und dem Aufbrechen der K-Schale bei der Ransilschen Zustandsfunktion.

Statistical Theory of Breakup Reactions
We propose an alternative for Coupled-Channels calculations with looselybound exotic nuclei(CDCC), based on the the Random Matrix Model of the statistical theory of nuclear reactions. The coupled channels equations are divided into two sets. The first set, described by the CDCC, and the other set treated with RMT. The resulting theory is a Statistical CDCC (CDCCs), able in principle to take int...
متن کاملBeyond the coherent coupled channels description of nuclear fusion.
New measurements of fusion cross sections at deep sub-barrier energies for the reactions 16O+{204,208}Pb show a steep but almost saturated logarithmic slope, unlike 64Ni-induced reactions. Coupled channels calculations cannot simultaneously reproduce these new data and above-barrier cross-sections with the same Woods-Saxon nuclear potential. It is argued that this highlights an inadequacy of th...
متن کاملCalixmexitil: Calixarene-based Cluster of Mexiletine with Amplified Anti-myotonic Activity as A Novel Use-dependent Sodium Channel Blocker
Mexiletine as the first choice drug in myotonia treatment is a chiral sodium channel blocker clinically used in its racemic form. The phenolic structure of this drug, prompted us to design its novel calix[4]arene-based cluster in a chalice-shaped structure. Therefore, the present study reports the synthesis and in-vitro anti-myotonic activity of the chalice-shaped cluster of mexiletine...
متن کاملComparison of Copper-61 Radioisotop Production Yield via Reactions of 64Zn(p,α)61Cu, natZn(p,x)61Cu, 61Ni(p,n)61Cu, and natNi(p,x)61Cu in Hospital Cyclotron using TALYS, EMPIRE, and MCNPX Nuclear Codes
Background & Aims: Copper-61 (61Cu) is a radioisotope with a half-life of 3.33 hours which decays to nickel-61 isotope byβ+ emission (61%) or electron capture (39%). This radioisotope can be used in the evaluation of the blood supply of the heart and low-oxygen cancer tissues imaging with PET. 61Cu is mainly produced by bombarding zinc (Zn), nickel (Ni) and cobalt (Co) targets in medium cyclot...

متن کاملAnti-Nuclear Antibodies in Patients with Polycystic Ovary Syndrome before and after Laparoscopic Electrocauterization
Polycystic ovary syndrome (PCOS) has been suggested to be linked with autoimmune processes. Laparoscopic ovarian electrocauterization has the potency to stimulate more autoimmune reactions in PCOS patients. In the present study, we considered anti-nuclear antibodies (ANAs) as the hallmark of autoimmune reactions, and investigated the serum level of these antibodies in 35 patients with PCOS (21-...
