Independent isomeric yield ratios of 95m,gNb in the natMo(γ, pxn) and natZr(p, xn) reactions

Isomeric pair 95 m,g Nb in the photonuclear reactions on natMo at the bremsstrahlung end-point energy of 38–93 MeV

“…The experimental results from Refs. [21][22][23] agree with each other, while the data from Refs. [16][17][18][19][20] obtained in different representations of the value IR contradict each other.…”

“…[18]). The IR values can also be found as the ratio of the yield for the formation of a product nucleus in the high-spin state to the yield for the low-spin state : [21,22]. These values will be equal to each other if the nucleus in the metastable state has a larger spin.…”

“…For a detailed study of this process, one needs to use the values of experimental cross-sections and IR values of multiparticle photonuclear reactions in a wide range of atomic mass and energies. However, there is still a lack of such Experiments on the photodisintegration of stable isotopes of the Mo nucleus and determination of the IR values of the nuclide products from the reaction were described in previous literature [16][17][18][19][20][21][22][23], using beams of bremsstrahlung photons and the residual γactivity method.…”

“…In Ref. [21], the values of were obtained based on 96 Mo , 97 Mo , and 98 Mo reactions, which was the first measurement with nat Mo targets at = 50, 60, and 70 MeV. In Ref.…”

Measurement of isomeric yield ratios in the photo-production of 133m,g;137m,g Ce from nat Ce using 55-, 60-, and 65-MeV bremsstrahlung

“…However, the cross-sections and the isomeric yield ratios in the photon-induced reactions above 35 MeV are very limited [27][28][29][30][31][32][33][34]. There is a cross section ratio measurement for the In the present work, the isomeric yield ratios for nat Ce(c,xn) 133m,g Ce and nat Ce(c,xn) 137m,g Ce reactions were measured at the end-point bremsstrahlung energies of 55-, 60-, 65-MeV by using the activation and the off-line c-ray spectrometric technique.…”
