~11Li,~14Be和~17B核的软偶极共振模式

SOFT DIPOLE MODE OF (11)~Li, (14)~Be AND (17)~B NUCLEI

假定^(11)Li,^(14)Be和^(17)B核是由核芯和两个外层中子所组成,用Sum Rule探讨这类核的巨偶极共振,给出软偶极共振的能量和强度。结果与其它理论计算进行了比较。

Assuming that the 11Li, 14Be and 17B nuclei are composed of the core and two outer neutrons, we have investigated the giant dipole mode of these nuclei by sum rule approach. The excitation energy and the strength of the soft dipole mode are calculated and compared with other theoretical results.
