In-beam fast-timing measurements in 103,105,107Cd

Fast-timing measurements were performed recently in the region of the medium-mass 103,105,107Cd isotopes, produced in fusion evaporation reactions. Emitted gamma-rays were detected by eight HPGe and five LaBr3:Ce detectors working in coincidence. Results on new and re-evaluated half-lives are discussed within a systematic of transition rates. The $7/2_1^+$ states in 103,105,107Cd are interpreted as arising from a single-particle excitation. The half-life analysis of the $11/2_1^-$ states in 103,105,107Cd shows no change in the single-particle transition strength as a function of the neutron number

Fast-timing measurements in 95,96Mo

Half-lives of the 19/2+ and 21/2+ states in 95Mo and of the 8+ and 10+ states in 96Mo were measured. Matrix elements for yrast transitions in 95Mo and 96Mo are discussed.Comment: Proceedings of XIX International School on Nuclear Physics, Neutron Physics and Applications, Varna, Bulgaria, 2011, 5 pages, 6 figure

The LAGUNA design study- towards giant liquid based underground detectors for neutrino physics and astrophysics and proton decay searches

The feasibility of a next generation neutrino observatory in Europe is being considered within the LAGUNA design study. To accommodate giant neutrino detectors and shield them from cosmic rays, a new very large underground infrastructure is required. Seven potential candidate sites in different parts of Europe and at several distances from CERN are being studied: Boulby (UK), Canfranc (Spain), Fr\'ejus (France/Italy), Pyh\"asalmi (Finland), Polkowice-Sieroszowice (Poland), Slanic (Romania) and Umbria (Italy). The design study aims at the comprehensive and coordinated technical assessment of each site, at a coherent cost estimation, and at a prioritization of the sites within the summer 2010.Comment: 5 pages, contribution to the Workshop "European Strategy for Future Neutrino Physics", CERN, Oct. 200

The LBNO long-baseline oscillation sensitivities with two conventional neutrino beams at different baselines

The proposed Long Baseline Neutrino Observatory (LBNO) initially consists of $\sim 20$ kton liquid double phase TPC complemented by a magnetised iron calorimeter, to be installed at the Pyh\"asalmi mine, at a distance of 2300 km from CERN. The conventional neutrino beam is produced by 400 GeV protons accelerated at the SPS accelerator delivering 700 kW of power. The long baseline provides a unique opportunity to study neutrino flavour oscillations over their 1st and 2nd oscillation maxima exploring the $L/E$ behaviour, and distinguishing effects arising from $\delta_{CP}$ and matter. In this paper we show how this comprehensive physics case can be further enhanced and complemented if a neutrino beam produced at the Protvino IHEP accelerator complex, at a distance of 1160 km, and with modest power of 450 kW is aimed towards the same far detectors. We show that the coupling of two independent sub-MW conventional neutrino and antineutrino beams at different baselines from CERN and Protvino will allow to measure CP violation in the leptonic sector at a confidence level of at least $3\sigma$ for 50\% of the true values of $\delta_{CP}$ with a 20 kton detector. With a far detector of 70 kton, the combination allows a $3\sigma$ sensitivity for 75\% of the true values of $\delta_{CP}$ after 10 years of running. Running two independent neutrino beams, each at a power below 1 MW, is more within today's state of the art than the long-term operation of a new single high-energy multi-MW facility, which has several technical challenges and will likely require a learning curve.Comment: 21 pages, 12 figure

Fast-timing lifetime measurements of excited states in Cu-67

The half-lives of the 9/2(+), 13/2(+), and 15/2(+) yrast states in the neutron-rich Cu-67 nucleus were determined by using the in-beam fast-timing technique. The experimentally deduced E3 transition strength for the decay of the 9/2(+) level to the 3/2(-) ground state indicates that the wave function of this level might contain a collective component arising from the coupling of the odd proton p(3/2) with the 3(-) state in Ni-66. Theoretical interpretations of the 9/2(+) state are presented within the particle-vibration weak-coupling scheme involving the unpaired proton and the 3(-) state from Ni-66 and within shell-model calculations with a Ni-56 core using the jj44b residual interaction. The shell model also accounts reasonably well for the other measured electromagnetic transition probabilities

Comparação termohigrométrica de sub-altitude em área urbana e rural em São Carlos, Brasil, por meio de VANT/DRONE.

A Radiossondagem de sub-altitude tem como objetivo mensurar os dados climatológicos em vários níveis verticais da atmosfera por meio de um equipamento denominado radiossonda. Além do mais, é conhecido que os diferentes tipos de uso e ocupação do solo (urbano, industrial, rural, florestal) alteram o balanço de energia entre a superfície e a atmosfera. Dessa forma, o estudo proposto tem como objetivo analisar e comparar os valores de temperatura e umidade relativa do ar próximo a superfície (1,5m de altura) e em diferentes alturas (50m e 190m da superfície) em área urbana e rural no município de São Carlos, Brasil, no período noturno em episódios de inverno, por meio de termohigrômetros acoplados em um Veículo Aéreo Não-Tripulado (Vant/Drone) do tipo quadricóptero (quatro hélices). O voo na área urbana foi realizado no dia 13/07/2018 e na área rural no dia 26/07/2018 entre 19:30 e 20:30. Os resultados demonstraram que na área urbana em períodos noturnos a temperatura e umidade relativa do ar são maiores próxima a superfície em relação aos dados de sub-altitude. Já na área rural em períodos noturnos a temperatura do ar é menor e a umidade relativa do ar é maior próximo a superfície em comparação aos dados de sub-altitude
