πg_(9/2)νh_(11/2) doublet bands in A～100 mass region
《Chinese Physics C》2009年第S1期37-39,共3页王守宇 张双全 亓斌 孟杰 
Supported by National Natural Science Foundation of China (10875074, 10605001, 10435010, 10221003, 10505002)
Using the model with one particle and one hole coupled with a triaxial rotor, the πg9/2/1/2νh11/2 doublet bands in the A～100 mass region are studied, and compared with the πg9/2/1/2νh11/2 doublet bands. It is fou...
