Restoration of rotational symmetry in deformed relativistic mean-field theory
《Chinese Physics C》2009年第S1期21-23,共3页尧江明 孟杰 Pena Arteaga Daniel Ring Peter 
Supported by Asia-Europe Link Project [CN/ASIA-LINK/008 (094-791)] of European Commission;National Natural Science Foundation of China (10435010, 10575083, 10605001, 10221003), DFG Cluster of Excellence "Origin and Structure of the Universe"(www.universe-cluster.de)
We report on a very recently developed three-dimensional angular momentum projected relativistic mean-field theory with point-coupling interaction (3DAMP+RMF-PC). Using this approach the same effective nucleon-nucleon...

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...
