【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(Epshell)、对能(Eppair和Enpair)和有效对能隙(Δp和Δn)等物理量和能shell和En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 S_2p and S_2n , the two-nucleon gaps δ_2p and δ_2n, the shell correction energies E^p_shell and Eⁿ_shell, the pairing energies E^p_pair and Eⁿ_pair, and the pairing gaps Δ_p and Δ_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
