Mixing effects on K-forbidden transition rates from the 6 isomers in the N = 104 isotones
نویسندگان
چکیده
The problem of the very different E2 decay rates from the two-quasineutron K = 6 isomers in the N = 104 isotones Er, Yb, Hf, and W is investigated using the triaxial projected shell model with inclusion of multi-quasiparticle configurations. It is demonstrated that the highly K-forbidden transition from the 6 isomer to the ground-state band is sensitive to mixing with the 6 state of the γ-vibrational band. Thus the inter-band transitions, and lifetimes, depend on the relative position of the γ-band and the isomeric state in each isotone.

Investigation of the Kπ = 8− Isomers in N=74 Isotones on Beam of the Warsaw Cyclotron
The decay of the K= 8− isomers in Ce and Nd have been investigated on the beam of the Warsaw Cyclotron using OSIRIS array. Reactions Sn(O,4n)Ce and Sn(Ne,4n)Nd were used. Two new decay paths have been found in the deexcitation of the 8− isomer in Ce. The hindrance factors for the E1, M2 and E3 transitions deexciting the isomer have been determined. Similar E3 decay of the 410 μs isomeric state ...

متن کاملQuarks, diquarks, and QCD mixing in the N resonance spectrum
We identify a ‘‘ selection rule’’ for N resonances in the presence of QCD mixing effects. We quantify these mixing effects from existing data and predict amplitudes for exciting 20 representations in SU(6), which are forbidden in strict diquark models. By classifying Particle-Data-Group (PDG) states at N 2, we show that N ! K , K , K , K , and J= ! pN are ideal probes of baryon dynamics and for...

A Laser Induced Fluorescence technique (LIF) has been used to study the mixing behavior of two emerging streams in a T-Type mixing chamber. A mixing index on the basis of digital image light intensities is calculated. It has been shown that averaging over more than 800 images leads to a stable mixing index calculation. Moreover, the effect of equal and un-equal flow rates on the mixing behavior...
