16. Fragment Mass Distributions in Neutron-Induced Fission of 232Th and 238U from 10 to 60 MeV
Sammanfattning : Since its discovery, the phenomenon of nuclear fission is the object of extensive theoretical and experimental studies. However, we are still far from a complete understanding of the fission process. LÄS MER
17. Response of the PANDA electromagnetic calorimeter to photons with energies below 100 MeV
Sammanfattning : Characteristics of the electromagnetic calorimeter of PANDA (anti-Proton ANnihilations at DArmstadt), one of the key experiments at FAIR, have been measured at the tagged photon beam facility at MAX-lab for 61 energies in the range 12-63 MeV. The tested detector array consisted of 5x5 PbWO4 (lead tungstate) crystals designed for the forward end-cap. LÄS MER
18. η Meson Production in Proton-Proton Collisions at Excess Energies of 40 and 72 MeV
Sammanfattning : The production of η mesons in proton-proton collisions has been studied with the WASA detector using internal pellet targets in the CELSIUS storage ring at the The Svedberg Laboratory in Uppsala. Data were taken at two beam energies, 1360 MeV and 1445 MeV, corresponding to CM excess energies of 40 and 72 MeV, respectively. LÄS MER
19. Experimental Studies of the Synthesis and the Survival Probability of Transactinides
Sammanfattning : In 1999 scientists in Dubna announced the successful synthesis of the nucleus 283112 by the reaction 48Ca+ 238U, with a cross-section of 5.0 pb. The isotope was found to decay by spontaneous fission (t1/2=81 s). LÄS MER
20. Meson production in pd collisions
Sammanfattning : Meson production in proton-deuteron collisions has been studied using the WASA detector facility at the CELSIUS storage ring in Uppsala. Data were obtained at two different beam energies, 1360 MeV and 1450 MeV, slightly above threshold for η and ω mesons. LÄS MER
