The fully self-consistent Hartree-Fock (HF) plus random phase approximation (RPA) based on Skyrme-type interaction is used to study the existence problem of proton semi-bubble structure in the state of 34Si. The experimental excitation energy and the transition strength of the
state in 34Si can be reproduced quite well. The tensor effect is also studied. It is shown that the tensor interaction has a notable impact on the excitation energy of the
state and a small effect on the B(E2) value. Besides, its effect on the density distributions in the ground and
state of 34Si is negligible. Our present results with T36 and T44 show that the
state of 34Si is mainly caused by proton transition from
orbit to
orbit, and the existence of a proton semi-bubble structure in this state is very unlikely.
