The effects of internal quark structure baryons on the composition and neutron star matter with hyperons are investigated in quark-meson coupling (QMC) model. QMC model is based a mean-field description nonoverlapping spherical bags bound by self-consistent exchange scalar vector mesons. predictions this compared quantum hadrodynamic (QHD) calibrated to reproduce identical nuclear saturation properties. By employing density-dependent bag constant through direct field, found exhibit...
The lifetimes for the high spin levels of yrast band $^{110}$Cd has been measured. estimated B(E2) values decrease with increase in angular momentum. This is characteristic Anti magnetic rotation as reported $^{106,108}$Cd. However, alignment behavior completely different from its even-even neighbors.
