Subtraction method in the second random-phase approximation: First applications with a Skyrme energy functional
Physical Review C
We make use of a subtraction procedure, introduced to overcome double--counting problems in beyond--mean--field theories, in the second random--phase--approximation (SRPA) for the first time. This procedure guarantees the stability of SRPA (so that all excitation energies are real). We show that the method fits perfectly into nuclear density--functional theory. We illustrate applications to the monopole and quadrupole response and to low--lying 0^+ and 2^+ states in the nucleus ^16O. We showdoi:10.1103/physrevc.92.034303 fatcat:2muooa4hdnegdc75dilyrsdkea
