Abstract

Paulijev princip zabranjuje postojanje dva fermiona u istom stanju. Iako Paulijev princip ima dalekosežne posljedice, njegov uzrok još uvijek nije objašnjen. Što isto tako znači da taj princip može biti u određenoj, vrlo maloj, mjeri i narušen u nekim reakcijama. Moguća narušenja Paulijevog principa eksperimentalno su istraživana u traženju X-zraka emitiranih u prijelazima u jezgrama koji su inače zabranjeni Paulijevim principom. Na Fizičkom odsjeku PMF-a s dva HPGe detektora napravljena su mjerenja spektara X-zračenja iz pločice olova kroz koju prolazi određena struja, odnosno postoje dodatni slobodni elektroni koji mogu, u slučaju narušenja Paulijevog principa, emitirati X-zrake određenih energija u slučaju elektronskih prijelaza u popunjeno osnovno stanje olova. U ovom diplomskom radu analizirali su se podaci iz mjerenja. Obrada podataka napravljena je u programu ROOT.

Abstract (english)

The Pauli exclusion principle forbids the existence of two fermions in the same state. Although the Pauli principle has far-reaching consequences, its underlying cause is still unexplained. This also implies that the principle could, to a very small degree, be violated in certain reactions. Possible violations of the Pauli principle have been experimentally investigated by searching for X-rays emitted in transitions within nuclei that are otherwise forbidden by the Pauli principle. At the Department of Physics at the Faculty of Science, measurements of X-ray spectra from a lead plate, through which a certain current flows, were carried out using two HPGe detectors. This means that additional free electrons are present, which, in the event of a violation of the Pauli principle, could emit X-rays of specific energies during electron transitions to the filled ground state of lead. In this thesis, data from these measurements were analyzed. Data processing was performed using the ROOT program.
