When a boron nucleus (`_5^10B`) is bombarded by a neutron, an alpha-particle is emitted. Which nucleus will be formed as a result?

which a U^(238) nucleus original at rest , decay by emitting an alpha particle having a speed u , the recoil speed of the residual nucleus is

When ._(3)Li^(7) nuclei are bombarded by protons , and the resultant nuclei are ._(4)Be^(8) , the emitted particle will be

In Rutherford experiment generally the thin foil of heavy atoms like gold platinum etc have been used to be bombarded by the alpha- particles If the thin foil of light atoms like aluminium etc is used what difference would be observed from the above results

.^22 Ne nucleus after absorbing energy decays into two alpha- particles and an unknown nucleus. The unknown nucleus is.

The distance of the closest approach of an alpha - particle fired at a nucleus with kinetic energy K is r_(0) . The distance of the closest approach when the alpha -particle is fire at the same nucleus with kinetic energy 2K will be

A nucleus at rest undergoes a decay emitting an a particle of de - Broglie wavelength lambda = 5.76 xx 10^(-15)m if the mass of the daughter nucleus is 223.610 amu and that of alpha particle is 4.002amu , determine the total kinetic energy in the final state Hence , obtain the mass of the parent nucleus in amu (1 amu = 931.470 MeV//e^(2) )

Radioactive nuclei emit beta^- particles. Electrons exist inside the nucleus.
