Measurement of cross-sections for the 93Nb(p,n)93mMo and 93Nb(p,pn)92mNb reactions up to ∼20 MeV energy

Activation cross sections of deuteron-induced reactions on niobium up to 24 MeV

“…The γ-line at 263.049 keV (I γ = 57.4%) from the 93m Mo IT decay (T1/2 = 6.85 h) was measured after a cooling time of about 10 hours. The derived excitation function of the 93 Nb (d,2n) 93m Mo reaction is shown in Fig. 2 together with the earlier experimental data [5][6] [7] and the TENDL-2017 data [21].…”

“…We used the standard methods, such as the stacked-foil activation method and off-line γ-ray spectrometry. The stacked target was composed of 93 Nb (99.9% purity, Nilaco Corp., Japan) and nat Ti (99.6% purity, Nilaco Corp., Japan) foils for monitoring the beam parameters. Niobium is a mono isotopic element, 93 Nb.…”

“…The stacked target was composed of 93 Nb (99.9% purity, Nilaco Corp., Japan) and nat Ti (99.6% purity, Nilaco Corp., Japan) foils for monitoring the beam parameters. Niobium is a mono isotopic element, 93 Nb. The thicknesses of the Nb and Ti foils were 27.11 and 9.13 mg/cm 2 , respectively, which were estimated from measurement of surface area and weight of larger sheets.…”

“…The excitation function of the 93 Nb(d,x) 92m Nb reaction was determined from measurements of the γ-line at 934.44 keV (I γ = 99.15%) from the 92m Nb decay (T1/2 = 10.15 d). The count of the peak was obtained after a cooling time of 32 days.…”

“…Several reactions to produce 93m Mo were studied earlier, such as proton-(see e.g. [4] and references therein) and deuteron-induced reactions on Nb [ [11]. The experimental literature was surveyed in the EXFOR database [12].…”
