As we know the spontaneous fission of an odd nucleus to an 2 odd nuclei happens with high probability when (Z^2)/A is greater than or equals 45(adsbygoogle = window.adsbygoogle || []).push({});

The conclusion of this is attached in pdf file with the post using the liquid drop nucleus model to explain the problem

The question is here now, What the condition Will be if the fission is from even-even to 2 nucleus odd-odd?

this is different than the previous situation because here appears the term "delta" in Weizsäcker formula of binding energy (Weizsäcker formula is attached in the pdf), which have a value when the nucleus is even-even or odd-odd... this term isn't linear and is proportional with the term A^(-3/4) where A is the atomic mass...

How can I solve this problem?

Thanks you, If what I've written isn't clear please let me know i've got examination on next sunday and need a solution for this...

thanks
