【摘要】 在相对论连续谱Hartree—Bogoliubov(RCHB)理论框架下,在质子数Z=100—140和中子数N=Z+30-2Z+32等偶偶核中进行了超重球形双幻核的探索．采用的有效相互作用为 NL1,NL3,NLSH,TM1,TW-99,DD—ME1,PK1和PK1R．基于对双核子分离能(S2p和S2n)、双核子能隙(δ2p和δ2n)、壳修正能量(Eshellp和Eshelln)、对能(Epairp和Epairn)和有效对能隙(△p和△n)等物理量和能级结构的分析,预言了可能的质子幻数和中子幻数,并观察到在超重核区壳的弱化现象．更多还原

【Abstract】 The magic proton and neutron numbers are searched in the superheavy region with proton number Z=100 -140 and neutron number N=(Z+30) - (2Z+32) by the relativistic continuum Hartree-Bogoliubov (RCHB) theory with interactions NL1, NL3, NLSH, TM1, TW99, DD-ME1, PK1, and PK1R. Based on the two-nucleon separation energies S2pand S2n, the two-nucleon gaps δ2p and δ2n, the shell correction energies Eshellp and Eshelln , the pairing energies Epairp and Epair n, and the pairing gaps △p and △n, some proton numbers and neutron numbers are suggested to be the magic numbers within the present approach. The shell quenching phenomena are observed in the region of the superheavy nuclei.更多还原
