Abstract:

  Charge symmetry breaking potentials due to the exchange of pseudoscalar and vector mesons in mirror nuclei are considered. With the computation of coulmb energy along with the present charge symmetry breaking effects provide a reasonably accurate description of the binding energy differences between mirror nuclei.

Study of Electromagnetic Multipole Transition Half-Lives of One-Hole 15O-15N and One-Particle 17O-17F Mirror Nuclei

Energy spectrum and wave functions are obtained numerically with a potential consisting of Woods–Saxon, Coulomb, and spin–orbit coupling parts for the nuclei 15O, 15N, 17O, and 17F. The radial parts of the wave functions are used to calculate some matrix elements of electromagnetic transitions. These results are applied to calculate half-lives of low-lying exited states in the one-particle 17O ...

سهم برهمکنش‌های CSB در اختلاف انرژی بستگی هسته‌های آینه‌ای

  Nolen-Schiffer Anomaly in mirror nuclei due to the NN interactions with isospin mixing between T=0 and T=1 mesons of the same spin and parity are investigated. With the computation of coulomb energy along with the charge symmetry breaking (CSB) effects provide a reasonably accurate description of binding energy differences between  39ca- 39k- , 41cs- 41ca mirror nuclei.

Sum-over-states density functional perturbation theory: Prediction of reliable 13C, 15N, and 17O nuclear magnetic resonance chemical shifts

Sum-over-states density functional perturbation theory �SOS-DFPT� has been used to calculate 13C, 15N, and 17O NMR chemical shifts of 20 molecules, for which accurate experimental gas-phase values are available. Compared to Hartree–Fock �HF�, SOS-DFPT leads to improved chemical shift values and approaches the degree of accuracy obtained with second order Mo”ller–Plesset perturbation theory �MP2...

شکست تقارن در هسته های آینه ای 55Co و55Ni

  Yrast states in mirror nuclei 55Co and 55Ni have been populated with a radioactive ion beam using the Isotope Separator On-Line method. A shielded array of 7 Compton suppressed germanium detectors recorded reaction gamma-rays. For channel selection, an array of 128 independent silicon detectors was used to differentiate exit channels with different number of proton and alpha particles emitted...
