Structure of Light Nuclei - Part 2
- Ingo Wiedenhoever (Florida State University)
The landscape beyond the drip lines is filled will resonances containing unbound nucleons which are momentarily constrained by centrifugal and Coulombs barriers. The further one goes past the drip lines, the larger the number of unbound nucleons and the resonances decay by spitting out these unbound nucleons in steps. Each step consisting of the removal of either a single nucleon or pair of...
Located at the neutron drip-line, 24O is the heaviest doubly-magic isotope of the oxygen isotopic chain. As the Qβ value increases and the neutron separation energy in the daughter nucleus decreases for the neutron-rich nucleus, beta-delayed neutron emission becomes a dominant decay mode, and neutron energy measurement is vital in studying the beta decay to the neutron unbound states. Also,...
The isospin formalism describes protons and neutrons as two projections of the nucleon and provides a powerful tool for identifying and classifying states in the vicinity of the line of N= Z. Under the assumption that isospin is a good quantum number, a number of relations arise to de- scribe isobaric analogue states their properties. This provides access wealth of information, from tests of...
The disappearance of the N=20 shell closure in the so-called “island of inversion” around 32Mg is one of the most striking examples of the strength of nucleon-nucleon correlations. In this region, the quadrupole-deformed intruder configuration (based on a multi-particle multi-hole configuration) becomes the ground state, subverting the expected shell ordering predicted by a harmonic oscillator...
