Abstract
The neutron-rich nuclei near doubly magic
Sn have attracted considerable interest in both nuclear physics and nuclear astrophysics. For the particle-hole nuclei in this region, the low-lying and high core excitations have been well described by shell model calculations using the extended pairing plus multipole-multipole force model. However, there is a significant difference between experiment and theory in the high-spin level 17
of
Te. We intend to illustrate this difference through monopole interactions. For this purpose, the monopole corrections between
and
are investigated in
Te,
Sb, and
Sn. Some theoretical levels are connected to the (17
) state of
Te with the monopole correction (Mc) of
and the quadruple-quadruple force between the proton and neutron, i.e., levels 3
(8
) in
Sn, level 14
in
Te, and level 23/2
in
Sb. Their observations at lower energies can confirm the datum of level (17
) in
Te with an illustration of monopole effects and quadruple-quadruple force.
