Abstract

U ovom radu proučavane su nuklearne reakcije izazvane snopom litijevih iona 7Li, energije 16 MeV na metama 12C, 7LiF i 6LiF. Izlazne čestice detektirane su dvostranim silicijskim vrpčastim detektorom (Micron Semiconductor tip W1 debljine 1000 μm) čije je središte bilo postavljeno na kutu od 21,8° u odnosu na smjer ulaznog snopa. Iz prikupljenih podataka rekonstruirani su energijski spektri pobuđenja jezgara 6,7Li, 9,10Be, 12C, 19F i 15N te su identificirana pobuđena stanja u rasponu energija 0-10 MeV. Detekcijom izlaznih čestica identificirani su procesi raspršenja iona 7Li na jezgrama meta 7Li, 12C, 19F i 27Al, elastično raspršenje (6Li(7Li, 6Li)7Li) sa detektiranim ionima 7Li i 6Li te procesi prijenosa tritona 7Li(7Li, α)10Be, 6Li(7Li, α)9Be, 12C(7Li, α)15N.

Abstract (english)

The Diploma thesis examines nuclear reactions studied on multiple targets (12C, 7LiF, 6LiF) induced by the 7Li beam at energy of 16 MeV. The emitted particles were detected with double sided silicon strip detector (Micron Semiconductor type W1, 1000 μm of thickness) whose center was positioned at an angle of 21,8°to incident beam. Collected data was used for excitation energy spectra reconstruction of 6,7Li, 9,10Be, 12C, 19F and 15N nuclei. Based on the data, excitation states were identified in energy range of 0-10 MeV. Detected nuclear reactions include elastic and inelastic scattering of 7Li on 7Li, 12C, 19F and 27Al, detection of scattered 6Li from 6Li(7Li, 6Li)7Li reaction and triton cluster transfer reactions 7Li(7Li, α)10Be, 6Li(7Li, α)9Be, 12C(7Li, α)15N.
