Step 1
First, we need to find the thickness of Al and Pb to transmit 10% of a narrow beam of 1-MeV gamma radiation. We can use the formula: I = I0 * e^(-Ī¼x) where I is the transmitted intensity, I0 is the initial intensity, Ī¼ is the linear attenuation coefficient, and Show moreā¦

Boron can absorb a slow neutron in the process ${ }^{1} n+{ }^{10} \mathrm{~B} \rightarrow{ }^{11} \mathrm{~B}+\gamma .$ Find the energy and wavelength of the emitted gamma ray.
In an accelerator experiment on high-energy collisions of electrons with positrons, a certain event is interpreted as annihilation of an electron-positron pair of total energy $10.2 \mathrm{BeV}$ into two $\gamma$ -rays of equal energy. What is the wavelength associated with each $\gamma$ -ray? $\left(1 \mathrm{BeV}=10^{9} \mathrm{eV}\right)$
