Studies of proton groups from the reaction F19(d, p)F20

Differential cross-section measurements for the 7Li(p,p0)7Li, 7Li(p,p1)7Li, 7Li(p,α0)4He, 19F(p,p0)19F, 19F(p,α0)16O and 19F(p,α1,2)16O reactions

“…Differential cross sections obtained in the present study for the 19 F(p,p 0 ) 19 F, 19 F(p,a 0 ) 16 nucleus, respectively, could not be analyzed separately, because of the coincidence of the corresponding peaks in the spectra for the proton energy range studied (due to the kinematics). Data are reported in the graphs with the corresponding statistical experimental errors along with data from the literature [9][10][11][12][13][14][15][16][17][18][19][20], when available, while the error bars along the x-axis (energy ripple of $0.16%) are not visible due to the adopted scale. Differential cross sections for the 19 F(p,p 0 ) 19 F reaction, plotted in Fig.…”

“…As far as fluorine is concerned, Proton Induced C-ray Emission (PIGE) is mainly used for the determination of its profile concentrations, due to the existence of several, narrow and strong resonances in the p+ 19 16 O reactions have been proposed in the past [9][10][11][12][13][14][15][16][17][18][19][20]. However, several differential cross-section datasets in the literature concerning various p+ 19 F reaction channels are discrepant in many cases, mainly because of the complicated resonance structures involved.…”

Differential cross-section measurements of the d+19F reaction channels for NRA purposes

“…Also, certain radiation safety precautions are mandatory due to the emitted neutrons from (d,n) reactions (on the target elements and structural materials), and/or deuteron breakup (for deuteron beam energies above 2.2 MeV). As far as d-NRA is concerned, differential cross-section data for the 19 F(d,a 0 ) 17 O, 19 F(d,p 0 ) 20 F and 19 F(d,p 1 ) 20 F reactions have been reported in literature [11][12][13] in the past.…”

“…More specifically, previous studies of the 19 F(d,p) 20 F and 19 F(d,a) 17 O reactions, that have been performed within the energy range E d = 800-2500 keV for the former reaction [11] and within the energy range E d = 710-2500 keV for the latter one [12,13] for only one backward angle at 150°, differ not only in the order of magnitude of the determined absolute differential cross-section values, but also in the shape of the corresponding excitation functions. The present study aims at contributing in this field, by resolving the discrepancies of the previous studies of the d + 19 F reaction channels and by adding new differential cross-section data in literature.…”

“…Column 4 gives the spectroscopic factors relativo to proton group Ps obtained by EL BEDEWI [7] at an energy of 9 MeV on the basis of BUTLER'S method. Proton groups Pi, P2 and Ps exhibir stripping angular distributions corresponding to a neutron capture with orbital angular momentum In = 2; proton group Pll has orbital angular momentum In --1, and proton groups 1913 @/914 have orbital angular momentum 1~ = 0. h should be noted here that the angular distributions of proton groups p~, P2,/gs,/913 @ Pl.~ also exhibit a stripping nature in the energy range Ea 1.5--2.5 MeV, whereas that of proton group Pll is very energy dependent [3,4]. The experimentally determined angular distributions of the other proton groups involved in these investigations P0, P:~, P4, P£ P0 eould not t)e fitted with the DWBA model.…”
