“…In Fig. 3 this ratio is plotted for 150 Sm and 152 Gd as a function of spin I, pairing both the 0 2 + and octupole bands and also pairing the ground state and octupole bands, and compared with the well established [22,38] octupole deformed nucleus 220 Ra. It is clear that for the comparison with the 0 2 + band, the ratio for 150 Sm is 1.0 within 5% from I = 5 onwards and is near 0.9 for 152 Gd.…”

“…This would suggest that the 0 2 + and octupole bands may form a reflection asymmetric structure with simplex quantum 044333-3 + band and octupole band, for 152 Gd and 150 Sm. They are compared with the established octupole deformed band in 220 Ra [22,38]. For structures with permanent octupole deformation, this ratio would be 1.0. number s = 1, rather than the ground state and octupole bands as suggested in Ref.…”

Knowledge of the exact microscopic structure of the 0 1 + ground state and first excited 0 2 + state in 150 Sm is required to understand the branching of double β decay to these states from 150 Nd. The detailed spectroscopy of 150 Sm and 152 Gd has been studied using (α,xn) reactions and the γ -ray arrays AFRODITE and JUROGAM II. Consistently strong E1 transitions are observed between the excited K π = 0 2 + bands and the lowest negative parity bands in both nuclei. These results are discussed in terms of the possible permanent octupole deformation in the first excited K π = 0 2 + band and also in terms of the "tidal wave" model of Frauendorf.

“…There have been various attempts before to estimate the effect of non-zero neutrino mass and mixing on the expected neutrino signal from a galactic supernova. Matter enhanced resonant flavour conversion has been observed to have a large effect on the ν e signal [15,16,17]. Theν e events of course remain unchanged in this case.…”

“…With vacuum oscillations we can expect an increase in both the ν e andν e signal. Burrows et al [16] have considered for SNO, the effect of vacuum oscillations as well and have found that with two-flavours the effect of vacuum oscillations on the signal is small, using their model predictions for the different ν luminosities.…”

“…The cross-section of the (ν e (ν e )−e − ) and (ν x −e − ) scattering has been taken from [27] while the neutral current (ν x − 16 O) scattering cross-section is taken from [23]. For the 16 O(ν e − e − ) 16 F and 16 (ν e , e + ) 16 N reactions we refer to [26] where we have used the cross-sections for the detector with perfect efficiency. From a comparison of the predicted numbers in Table 1, it is evident that neutrino oscillations play a significant role in supernova neutrino detection.…”

Abstract:Neutrinos and antineutrinos of all three flavours are emitted during the post bounce phase of a core collapse supernova with ν µ /ν τ (ν µ /ν τ ) having average energies more than that of ν e (ν e ). They can be detected by the new earth bound detector like SNO and Super-Kamiokande which are sensitive to neutrinos of all three flavours. In this letter we consider the effect of flavour oscillations on the neutrino flux and their expected number of events at the detector. We do a three-generation analysis and for the mass and mixing schemes we first consider the threefold maximal mixing model consistent with the solar and the atmospheric neutrino data and next a scenario with one ∆m 2 ∼ 10 −11 eV 2 (solar range) and the other ∆m 2 ∼ 10 −18 eV 2 , for which the oscillation length is of the order of the supernova distance. In both these scenarios there are no matter effects in the resultant neutrino spectrum and one is concerned with vacuum oscillations. We find that though neutrino oscillations result in a depletion in the number of ν e andν e coming from the supernova, the actual signals at the detectors are appreciable enhanced.

We review the application of non-Abelian discrete groups to Tri-Bimaximal (TB) neutrino mixing, which is supported by experiment as a possible good first approximation to the data. After summarizing the motivation and the formalism, we discuss specific models, mainly those based on A4 but also on other finite groups, and their phenomenological implications, including the extension to quarks. The recent measurements of θ13 favour versions of these models where a suitable mechanism leads to corrections to θ13 that can naturally be larger than those to θ12 and θ23. The virtues and the problems of TB mixing models are discussed, also in connection with lepton flavour violating processes, and the different approaches are compared.
