摘要：
The excitation of Gamow-Teller (GT) and Isovector Spin Monopole (IVSM) modes in In-116 by (p,n) and (n,p)) charge-exchange reactions is studied within the framework of the Quasiparticle Random-phase Approximation. It is shown that the admixture of the IVSM and Gamow-Teller (GT) excitations is negligible, and that the contribution to the strength above 20 MeV excitation energy, in In-116, is, most likely, due to the IVSM (sigma r(2)tau(+/-)) mode.
