متن کاملEffects of Neutron-proton Interaction in Doubly Odd Deformed Nuclei
As is well known, the two most important effects associated with the residual interaction between the odd neutron and the odd proton in doubly odd deformed nuclei are the Gallagher-Moszkowski (GM) splitting [1] and the Newby (N) shift [2]. In addition relevant information may be provided by the study of the odd-even staggering in K 6= 0 bands [3, 4]. In fact, this effect may be traced to direct...
متن کاملA / I ? + Gamow - Teller strength in nuclei
The distribution of p+ Gamow-Teller strength in 26Mg, 54Fe and 56Ni is calculated in the QRPA and large-basis shell-model spaces. The quenching relative to the simplest jj coupled model found in the QRPA is similar to that found in a shell-model basis which includes 2p2h ground-state correlations within the major shell (sd or pf). For 26Mg there is significant additional quenching found in the ...
متن کاملObservation of low- and high-energy Gamow-Teller phonon excitations in nuclei.
Gamow-Teller (GT) transitions in atomic nuclei are sensitive to both nuclear shell structure and effective residual interactions. The nuclear GT excitations were studied for the mass number A = 42, 46, 50, and 54 "f-shell" nuclei in ((3)He, t) charge-exchange reactions. In the (42)Ca → (42)Sc reaction, most of the GT strength is concentrated in the lowest excited state at 0.6 MeV, suggesting th...
متن کاملQuasi-Deuteron Configurations in odd-odd N=Z nuclei
The isovector M1 transitions between low-lying T=1 and T=0 states in oddodd N=Z nuclei are analyzed. Simple analytical expressions for M1 transition strengths are derived within a single-j-shell approximation for both j = l+1/2 and j = l − 1/2 cases. The large B(M1) values for the j = l + 1/2 case are attributed to quasi-deuteron configurations. The B(M1) values for the j = l − 1/2 case are fou...
