Studies of some isomeric yield ratios produced with bremsstrahlung

Measurement of isomeric yield ratios in natIn and natSn with 50, 60, and 70 MeV bremsstrahlung photons

“…[16][17][18][19][20][21][22][23][24][25] in the wide energy range found in the literature are given in Table 3. The total uncertainties in Table 3 consist of two parts listed in Table 4: one is the uncertainty related to the measurement which is calculated from Eq.…”

“…3a-d we plotted the present results together with the existing literature data for the nat In(c,xn) 110m,g In, nat In(c,xn) 111m,g In, nat In(c,xn) 112m,g In, and nat Sn(c,xnp) 117m,g In reactions as a function of the incident bremsstrahlung energies. For the nat In(g,xn) 110m,g In reaction, there is only one measurement reported by Kolev [17] at 43 MeV bremsstrahlung as shown in Fig. 3a.…”

“…Dependence of isomeric yield ratios on the incident bremsstrahlung energy of (a) 110m,g In, (b) 111m,g In, (c) 112m,g In, and (d) 117m,g In. [17] also measured the isomeric yield ratios of 111m,g In and 112m,g In isomeric pairs using the nat In sample at 43 MeV bremsstrahlung beam. Demekhina et al [18] recently measured the isomeric yield ratio of 112m,g In using the enriched 113 In sample at 30 MeV bremsstrahlung photon.…”

“…Kolev [17] has measured the IR values of 112m,g In, 111m,g In, and 110m,g In from nat In target with bremsstrahlung energy of 43 MeV. The most recent investigation of the IR of 112m,g In was conducted by Demekhina et al [18] with 30 MeV bremsstrahlung.…”

Activation cross sections for the (γ,n) reactions on zirconium isotopes

“…There are many experiments to measure 90 Zr(c,n)89 m,gZr reaction around the GDR region to 43-MeV (Bodrov et al, 1994;Davydov et al, 1987;Palvanov and Razhabov, 1999;Kolev, 1998;Demekhina et al, 2002). The Giant Dipole Resonance.…”
