Cross section measurements of theY89(p,γ)Zr90reac

Measurements of proton-induced reaction cross sections onTe120for the astrophysicalpprocess

“…The last decade has seen an increased interest in measuring the proton capture cross sections of p-nuclei [10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25]. The bulk of these (p,γ) measurements have been done in the lower mass region (A < 100).…”

“…Variations can lead to substantial changes in p-process abundance predictions. There is considerable effort to experimentally test the reliability of p-process predictions on selected cases [6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25]. Since the photodisintegration process 121 I(γ, p) directly feeds 120 Te, this reaction provides an excellent case for testing the reliability of the Hauser-Feshbach prediction near the closed proton shell Z=50; 121 I has a high level density near the proton threshold and the reaction should be eligible for the statistical model prediction [26].…”

“…The relevant astrophysical reaction rates can be determined from the cross section of the inverse capture reactions through the detailed balance theorem if the corresponding capture cross sections are known experimentally. In the last few years several proton capture cross section measurements for p process studies were carried out [5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]. However, it has been shown recently that not only (γ,p) reactions are important for modeling the synthesis of the light p nuclei, but (n,p) and (p,n) reactions should also be taken into account [4].…”

Proton capture reaction cross section measurements on Er162 as a probe of statistical model calculations

“…The corresponding cross section, calculated with the TALYS reaction code [17], is between 10 −8 and 10 −3 b respectively. The bulk of (p,γ ) measurements have been performed in the lower mass region (A < 112) [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36], except for 120 Te [37], 130 Ba [38], and 152 Gd [39]. For the (p,n) channel, very few (p,n) measurements have been performed, with the exception of 76 Ge [20], 82 Se [21], 85 Rb [34], 120 Te [37], 130 Ba [38], and 152 Gd [39].…”
