In this work the absolute differential cross sections of the 18O(d,pγ)19O (Eγ = 1376 keV) ,18O(d,nγ)19F (Eγ = 1357 keV) and 16O(d,pγ)17O (Eγ = 871 keV) reactions were measured for the isotopic analysis of oxygen by DIGE technique. The energy of the incident deuterons was varied from 590 to 1994 keV in steps of 10 keV. Gamma-rays and backscattered deuterons were collected simultaneously by an HPGe detector at an angle of 90° and an ion implanted Si detector at a scattering angle of 165° with respect to the beam direction. An anodic Ta216,18O5 thin layer on tantalum was used throughout the cross sections measurement. The validity of obtained cross sections was checked by benchmarking experiment with a thick Y2O3 target. The overall systematic uncertainty of the measured cross section data was estimated to be better than 9%.

Differential cross sections of the 24 Mg(d,p 0,1,2,3,4 ) reactions were obtained in the range E d,lab = 1.2–2 MeV and at the scattering angles of 90°, 135°, 150° and 165° using a thin Mg target having thickness of 76.7 ± 3.1 μg/cm 2 . The cross section values were determined with an average energy step of ∼25 keV while the detailed measurements were carried out with an energy step of ∼5 keV around the resonance peaks. Elastic scattering data for three steep backward angles (135°, 150° and 165°) were also studied for the same incident deuteron energy range and steps. The results were compared with those of the previous studies. Moreover, the validity of the measured data has been benchmarked using a thick Mg target at two deuteron beam energies of 1.7 and 2 MeV.

In the present work, differential cross section values of the 16O(d,d0) reaction were obtained for Ed,lab = 900–2000 keV, at four scattering angles, namely at 90°, 135°, 150° and 165° using a thin SiO target having a thickness of (910 ± 36) × 1015 at/cm2. The cross section values were determined with an energy step of ∼10 keV while, the detailed measurements were carried out with an energy step of ∼5 keV around the resonance peaks. The results were compared with those of the previous studies.

Nuclear Reaction Analysis (NRA) and more specifically d-NRA is a suitable technique for 16 O detection on or near surface of a compound containing heavy elements. The main problem of d-NRA is the limited number of NRA differential cross section data sets and their differences. The differential cross sections of 16 O(d,p 0,1 ) reactions were measured in the present work for E d,lab = 700–1800 keV, at four scattering angles, namely at 90°, 135°, 150° and 165° which are suitable for NRA. Differential cross sections were collected with an energy step of ∼10 keV. However, detailed measurements were carried out with an energy step of ∼2 keV around resonances. The results are compared with previous studies and the similarities and differences are discussed.

Positron Annihilation Lifetime and Doppler Broadening spectroscopy of positron annihilation radiation are performed in four different polymers. The size of elementary free volume sites and their chemical environments are determined. It is shown that polymers with different groups of C–H, C O, and C–F can be distinguished by their orbital electron momentum spectrum. Correlation between parameters of the PALS and CDBS techniques in situations involving O-Ps formation at different chemical environments are clarified. The results indicate that both the S and W-parameters show a linear correlation with the size of elementary free volume sites of the polymers. Moreover, for polymers belonging to C O and C–F groups, the effect of positron trapping by polar groups on the probability of O-Ps formation is discussed.
