The Jiangmen Underground Neutrino Observatory (JUNO), a 20 kton multi-purpose underground liquid scintillator detector, was proposed with the determination of neutrino mass hierarchy as primary physics goal. It is also capable observing neutrinos from terrestrial and extra-terrestrial sources, including supernova burst neutrinos, diffuse background, geoneutrinos, atmospheric solar well exotic searches such nucleon decays, dark matter, sterile etc. We present motivations anticipated...
This document reports on a series of experimental and theoretical studies conducted to assess the astro-particle physics potential three future large-scale particle detectors proposed in Europe as next generation underground observatories. The apparatus employ different and, some extent, complementary detection techniques: GLACIER (liquid Argon TPC), LENA scintillator) MEMPHYS (\WC), based use large mass liquids active media. results these are presented along with critical discussion...
In recent experiments at the velocity filter Separator for Heavy Ion reaction Products (SHIP) (GSI, Darmstadt), an extended and improved set of α-decay data more than 20 most neutron-deficient isotopes in region from lead to thorium was obtained. The combined analysis this newly available data, which (186)Po decay is reported here, allowed us first time clearly show that crossing Z = 82 shell higher proton numbers strongly accelerates α decay. From experimental α-particle formation...
An in-beam study of excited states in the transfermium nucleus 252No has been performed using recoil separator RITU together with JUROSPHERE II array at University Jyväskylä. This is second studied an experiment. Levels up to spin 20 were populated and compared levels 254No. upbend seen a frequency 200 keV/ħ corresponding 16. We also use improved systematics connect energy lowest 2+ state its half-life find that deformation both 252,254No slightly larger than previously assumed.Received July...
Abstract. The AGEMERA project (Agile Exploration and Geo-Modelling for European Critical Raw Materials) advances the exploration of critical raw materials in EU by deploying innovative, non-invasive geophysical technologies. Funded Horizon Europe programme, it aligns with Materials Act to enhance resource security sustainability. Utilising passive seismic methods, drone-based electromagnetic sensing, muography, maps subsurface characteristics across multiple countries Zambia. Outcomes are...
Very neutron deficient uranium isotopes were produced in fusion evaporation reactions using $^{40}\mathrm{Ar}$ ions on $^{182}\mathrm{W}$ targets. The gas-filled recoil separator RITU was employed to collect the products and separate them from scattered beam other reaction products. activities implanted into a position sensitive silicon detector after passing through gas-counter system. identified spatial time correlations between implants decays. Two $\ensuremath{\alpha}$-decaying states,...
Very neutron-deficient francium and radium isotopes have been produced in fusion evaporation reactions using $^{63}\mathrm{Cu}$ $^{65}\mathrm{Cu}$ ions on $^{141}\mathrm{Pr}$ targets $^{36}\mathrm{Ar}$ $^{170}\mathrm{Yb}$ targets. The gas-filled recoil separator RITU was employed to collect the products separate them from scattered beam. activities were implanted into a position-sensitive silicon detector after passing through gas-counter system. identified spatial time correlations between...
Abstract Muography is a novel imaging method using natural cosmic-ray radiation for characterising and monitoring variation in average material density diverse range of objects that cannot be imaged by conventional techniques. includes muon radiography tomography. Cosmic-ray-induced muons were discovered the 1930’s, but rapid development both muographic techniques has only occurred last two decades. With this development, muography been applied or tested many fields such as volcano imaging,...
In-beam γ-ray spectroscopic measurements have been made on 253102No. A single rotational band was identified up to a probable spin of 39/2ℏ, which is assigned the 7/2+[624] Nilsson configuration. The bandhead energy and moment inertia provide discriminating tests contemporary models heaviest nuclei. Novel methods were required interprete sparse data set associated with cross sections around 50 nb. These included comparisons experimental simulated spectra, as well testing for evidence in γγ...
