Item type:Item, ANOMALIES OF MOMENT OF INERTIA IN OS-170-180(1993-02-01) ;CHIANG, HC ;HSIEH, ST ;YEN, MMK ;CHUU, DS電子物理學系The anomalies of moment of inertia in 170-180Os are analysed in the interacting-boson-plus-fermion-pair model. The angular momentum-angular momentum interaction term (L.L) in the boson Hamiltonian is renormalized by a (1 + fL.L)- 1 factor. It was found that the renormalization facilitates the interaction parameter searching and all boson-boson and boson-fermion interaction parameters for the isotope chain can be unified. Energy levels can be reproduced quite well. The general features in the moment of inertia anomalies can be reproduced. The transition quadrupole moments are calculated and compared with other estimates.Item type:Item, EFFECTIVE BOSON CALCULATIONS ON SM ISOTOPES(1986-07-01) ;HSIEH, ST ;CHIANG, HC ;YEN, MMK ;CHUU, DS電子物理學系Item type:Item, NEGATIVE-PARITY STATES OF N=88 ISOTONES IN THE SDF BOSON PLUS A FERMION PAIR MODEL(1991-02-01) ;CHUU, DS ;HSIEH, ST ;YEN, MMK ;電子物理學系Department of ElectrophysicsThe energy levels of negative parity states of N = 88 isotones: Yb-158, Er-156 and Dy-154 are studied in terms of the SDF interacting boson approximation (IBA) model with one s- or d-boson being able to break and form a fermion pair. The fermion pair is allowed to occupy the iota-13/2 single particle orbit. It is found that the energy levels of the negative parity bands of these nuclei can be reproduced satisfactorily. The backbends of the moment of inertia can be also reasonably described.Item type:Item, SHELL-MODEL CALCULATIONS OF ONE-HOLE STATES IN THE NUCLEI OF A = 41-43(1983-01-01) ;CHUU, DS ;HAN, CS ;HSIEH, ST ;YEN, MMK電子物理學系Item type:Item, SHELL-MODEL STUDIES OF NEGATIVE-PARITY STATES IN NUCLEI WITH A=18, 19 AND 20(1982) ;YEN, MMK ;HSIEH, ST ;CHIANG, HC ;CHUU, DS電子物理學系Item type:Item, SHELL-MODEL STUDIES OF THE Y-90,ZR-91,NB-92 AND MO-93 NUCLEI(1979) ;CHUU, DS ;YEN, MMK ;SHAN, Y ;HSIEH, ST電子物理學系Item type:Item, STRUCTURES OF N=88 AND N=90 ISOTONES IN THE INTERACTING BOSON APPROXIMATION(1984-01-01) ;CHUU, DS ;HAN, CS ;HSIEH, ST ;YEN, MMK電子物理學系
