Change in ~7Be half-life in host media
First-principle calculations within the density functional theory framework are used to study the probability of electron capture for the ~7Be nucleus.For this purpose,electron density at the ~7Be nucleus is computed in Al,Au,Pd,Pt,and Pb environments.Our results show that the half-life of ~7Be is changed by implanting ~7Be in host environments.Electron affinity of the media and confinement effects are responsible for the change in the half-life of ~7Be nucleus.Moreover,electric potential at the ~7Be nucleus is calculated.Results show that variations in electric potential are usually consistent with those in electron density at the ~7Be nucleus.
