An isotope of beryllium 47Be^{7}_{4}\text{Be}47Be decays into an isotope of lithium (Li) by electron capture.
Complete the equation for this decay by filling in the blanks:
47Be+−10e→‾Li+‾ ^{7}_{4}\text{Be} + ^{0}_{-1}\text{e} \rightarrow \underline{\quad}\text{Li} + \underline{\quad} 47Be+−10e→Li+Name the fundamental interaction responsible for this decay and explain why it is the only interaction capable of this change.
After the decay, the lithium nucleus is in an excited state. It returns to its ground state by emitting a single gamma photon with an energy of 0.478 MeV0.478 \text{ MeV}0.478 MeV. Calculate the wavelength of this photon.
Another isotope, beryllium-10 (410Be^{10}_{4}\text{Be}410Be), decays by a different process to form boron-10 (510B^{10}_{5}\text{B}510B). Suggest what particles are emitted in this second process and how they could be detected to distinguish it from the electron capture decay of beryllium-7.
