spallation

GBK engleski na srpski Tehnika/inženjerstvo Nuklearni inženjering/nauka
Definition from European Nuclear Society:
Nuclear conversion during which an energy-rich bombardment particle knocks out numerous individual particles (protons, neutrons) from the target nucleus. Observed initially as an effect of cosmic radiation.
Example sentences:
There are many distinct methods of producing sufficiently strong neutron beams for science. Because of their flux (see below), that is higher by several orders of magnitude, nuclear reactors and spallation sources are nowadays preferred to radioisotope, photon or accelerator sources. (AUSTRON )
Finally, the pulsed proton beam will be directed onto a liquid mercury target, where 60-Hz pulses of neutrons will be created through spallation reactions of the protons with the mercury nuclei. (Spallation Neutron Source)
With the world's highest flux reactor-based neutron source (the High Flux Isotope Reactor) and the world's most intense pulsed accelerator-based neutron source (the Spallation Neutron Source), ORNL provides neutron scattering capabilities unavailable anywhere else in the world. (Oak Ridge National Laboratory)

Spalacija Proces u kom usled bombardovanja atomskog jezgra česticama visoke energije dolazi do oslobađanja određenog broja nukleona, što dovodi do smanjenja atomske mase jezgra.

Example sentence:

* Kao radioaktivni predak u afla emiterima koristi se neki od radionuklida nastalih u procesu raspada 232 U, 235 U ili 239 Th. Najpoznatiji je halogen 211 At. Dobija se ili raspadom pretka 211 Rn koji se dobija spalacijom torijuma ili bombardovanjem jezgra 209 Bi alfa česticama.

Example sentence was taken from "Radionuclides: Therapeutic Use", written by Jurij Vučina and Ruben Han [available at http://scindeks.nb.rs/article.aspx?artid=0025-81050106245V&r...]

[Popić R. et al, Naučno tehnički rečnik en-sr, Građevimsa knjiga, Beograd, 2005]
Definition from Vikipedija:
Spalacija u nuklearnoj fizici je proces u kojem iz teškog atomskog jezgra pogođenog protonom visoke energije izleće veliki broj slobodnih nukleona pri čemu se prvobitno jezgro pretvara u novo jezgro znatno manje atomske mase.
Example sentences:
Simulacija mehanizama spalacije i eksperimentalna provera pomoću trag detektora vrši se u Institutu “Vinča”. (Institut "Vinča")
Dovoljne aktivnosti, u nekim slucajevima, mogu se dobiti sarno visokoenergetskim nuklearnim reakcijama kao sto je spalacija. (Srpski citatni indeks)
Klasifikacija događaja izvršena je na osnovu multipliciteta teških fragmenata, MT, na događaje multifragmentacije (MT = 0), duboke spalacije i fragmentacije (MT = 1), i termalne binarne fisije i violentne fisije (MT = 2). (УНИВЕРЗИТЕТ У КРАГУЈЕ)
