Natural Tellurium competing reactions

Te-130(34%)

$\gamma + Te-130 \rightarrow Sb-129 + p \rightarrow Te-128 + \beta^- (4 hour half life)$

$\gamma + Te-130 \rightarrow Te-129 + n \rightarrow I-129 + \beta^- (70 min half life)$

I-129 is basically stable

I-129

$\gamma + I-129 \rightarrow Te-128 + p$

$\gamma +I-129 \rightarrow I-128 + n \rightarrow Xe-128 + \beta^- (25 min half life)$

Te-128 and Xe-128 are stable

Te-128(32%)

$\gamma + Te-128 \rightarrow Sb-127 + p \rightarrow Te-127 + \beta^-\rightarrow I-127 + \beta^-$

$\gamma + Te-128 \rightarrow Te-127 + n \rightarrow I-127 + \beta^-$

I-127 is stable

Te-126(19%)

$\gamma + Te-126 \rightarrow Sb-125 + p$

$\gamma + Te-126 \rightarrow Te-125 + n$

Te-123(1%)

Yield Problem: Te-120 is only 0.1% of the natural abundance. Highest natural abundance is Te-126 at 19%, then Te-125 at 7%, Te-124 at 5%, Te-122 at 2.5%, Te-123 at 1%.
