Nuclear tetrahedral states and high-spin states studied using quantum number projection method

摘要

We have recently developed an efficient method of performing the full quantumnumber projection from the most general mean-field (HFB type) wave functionsincluding the angular momentum, parity as well as the proton and neutronparticle numbers. With this method, we have been investigating several nuclearstructure mechanisms. In this report, we discuss the obtained quantumrotational spectra of the tetrahedral nuclear states formulating certainexperimentally verifiable criteria, of the high-spin states, focussing on thewobbling- and chiral-bands, and of the drip-line nuclei as illustrativeexamples.
