| Abstract: |
Designer nuclei are those nuclei that rarely exist in nature as stable nuclei. They are a consequence of the fabrication process at the scale of atomic nuclei. Designer atomic nuclei are new, rare isotopes, with unusual numbers of protons or neutrons with unusual decay modes. For instance, super heavy isotopes of light elements such as 113Li, have a very high ratio of neutrons to protons (N/Z = 8/3) such that the neutrons in 113Li have very low binding energy. The size of 113Liis roughly 10/fm= 10-14m(it stretches to a longer size) which corresponds to roughly ten times the volume of the stable 113Li6 nucleus, and it has the size of 86Ra 220 nucleus. The 113Li nucleus has a diffuse surface of neutron matter, and this is due the fact that quantum mechanically the wave function of the neutrons can extend far beyond the normal range of the nucleus. The existence of such nuclei allows the study of interaction of neutrons in pure neutron matter, such as neutrons stars, and also in the case of finite nuclei X Z N where N > Z. In such a system it can be assumed that the core of the nucleus is made up of Z neutron-proton pairs (deuterons) which are surrounded by the unpaired neutrons (N-Z). As the neutron number becomes very large compared to the proton number, variation of the charge radius of the nucleus can also be studied. Such calculations can assist in the development of new nuclear theory. [ABSTRACT FROM AUTHOR] |
