Najdôležitejšie výsledky:

1) fyzika neutrina:
•    Spektroskopia neutrin zo Slnka metodou tekuteho scintilatore (experiment Borexino v Laboratori Nazionali del Gran Sasso v Taliansku). Prve meranie neutrin z nasledovnych jadrovych reakcii prebiehajucich na Slnku: tzv. 7Be, pep neutrin, zmeranie 8B neutrin nad 3 MeV. Najsilnejsi experimentalny limit CNO neutrin.

•    Prve statisticky vyznamne zmeranie geoneutrin, neutrin pochadzajucich z radioaktivnych rozpadov 232Th a 238U v Zemi.

2) Spektoskopia exotickych atomov

•    Zmeranie “velkosti” protonu (proton charge radius) metodou laserovej spektroskopie atómu vodíka, ktorý má namiesto elektrónu muón (Lamb shift experiment v Paul Scherrer Institute vo Svajciarsku). Tato nova metoda priniesla prekvapivy vysledok, podla ktoreho proton je mensi, ako sa predpokladalo.

•    Spektroskopia atomu kaonickeho vodika, cize atomu vodika, ktory ma namiesto elektronu kaon. Kaon je negativne nabita castica co interaguje okrem elektromagnetickych interakcii, ktore “drzia” pohromade atomy, aj tzv. silnymi (jadrovymi) interakciami.

3) Geologia
•    Stadium metamorfneho vyvoja metapelitov z krystalinika Tatier, ich vyvoj v priestore teplota-tlak-cas pocas Variskeho orogenu.
