Which isotope on bombardment with $\alpha$-particles will give $_8O^{17}$ and $_1H^1$?

The missing particle in the reaction,$_{92}^{235}U + _{0}^{1}n \to _{56}^{146}Ba + ... + 3_{0}^{1}n$ is

If $_{92}U^{235}$ nucleus absorbs a neutron and disintegrates into $_{54}Xe^{139}$,$_{38}Sr^{94}$ and $X$,then what will be the product $X$?

Artificial transmutation was discovered by

In the nuclear reaction $_{12}Mg^{24} + _{2}He^{4} = _{0}n^{1} + ?$,the product nucleus is:

When $_3Li^7$ are bombarded with protons,$\gamma$-rays are produced. The nuclide formed is
