Measurement of isomeric-yield ratios of 109m,gPd and 115m,gCd with 50-, 60-, and 70-MeV bremsstrahlung

Isomeric Ratios 109m,gPd in the (γ, n) and (n, 2n) Reactions

“…in the 21-35 MeV interval, the energy dependence of the isomeric ratios of the yields of the reaction 110 Pd( , ) 109 , Pd was determined for the first time. The values of the isomeric yields obtained in [8] are slightly higher than those of other studies. It is possible that, at high energies, the isomeric ratio increases.…”

“…3, we present the energy dependence of the 110 Pd( , ) 109 Pd reaction cross-section obtained with the TALYS-1.6 software package. In [8], experimental results were obtained in the energy interval 10-18 MeV. The region of the giant dipole resonance is not completely covered.…”

“…Previously, isomeric ratios in the 110 Pd( , ) 109 , Pd reaction were measured in c ○ S. PALVANOV, T. AKHMADZHANOV, 2021 [5][6][7][8]. In [5,6,8], measurements were carried out at several points of the maximum energy of bremsstrahlung. In [7], isomeric ratios were measured in the energy interval 9-18 MeV.…”

Measurements of natCd(γ, x) reaction cross sections and isomer ratio of 115m,gCd with the bremsstrahlung end-point energies of 50 and 60 MeV *

“…For comparison, the nat Cd(γ, xn) 115g,m,111m,109,107,105, 104 Cd and nat Cd(γ, pxn) 113g,112,111g,110m Ag reaction cross sections were also theoretically calculated by employing the computer codes TALYS-1.95 [17] and . The IR values from the present study with the bremsstrahlung end-point energies of 50 and 60 MeV are compared with the calculated values [17,18] as well as with the available literature data [11][12][13][14][15].…”

“…) and low spin is known as the isomeric yield ratio [10]. There are few earlier experimental studies on the IR of 115m,g Cd produced from the 116 Cd(γ, n) 115m,g Cd reaction in the giant dipole resonance region [11][12][13][14], based on mono-energetic photon beams. However, the measured IR of g,m115 Cd in the 116 Cd(γ, n) reaction using bremsstrahlung endpoint energies of 50, 60, and 70 MeV is available in literature [15], and the IR at high neutron energies for the 116 Cd(n, 2n) 115m,g Cd reactions [16] is also cited.…”
