Study of weakly-bound odd-A nuclei with quasiparticle blocking

The coordinate-space Hartree Fock Bogoliubov (HFB) approach with quasiparticle blocking has been applied to study the odd-A weakly bound nuclei B-17,B-19 and Mg-37, in which halo structures have been reported in experiments. The Skyrme nuclear forces SLy4 and UNEDF1 have been adopted in our calculations. The results with and without blocking have been compared to demonstrate the emergence of deformed halo structures due to blocking effects. In our calculations, B-19 and Mg-37 have remarkable features of deformed halos.National Key Basic Research Program of China [2013CB83440]; National Natural Science Foundation of China [11375016, 11235001, 11320101004]; Research Fund for Doctoral Program of Higher Education of China [20130001110001]SCI(E)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)ARTICLEpeij@pku.edu.cn225-304
