Determine the percent abundance for J-67 and J-68, given the following data: The average atomic mass for J is 65.96 amu. Atomic % Isotope weight abundance J-64 |63.9296 6.744 J-66 65.9449 90.654 J-67 66.9154 ??

Please only answer part b. Thank you! (b) The negative muon (μ−) behaves like a heavy electron, with the same charge as the electron but with a mass 207 times as large as the electron mass. As a moving μ− comes to rest in matter, it tends to knock electrons out of atoms and settle down onto a nucleus to form a "one-muon" atom. For a system consisting of a nucleus of platinum (Pt195 with 78 protons and 117 neutrons) and just one negative muon, predict the energy in eV of a photon emitted in a transition from the first excited state to the ground state. The high-energy photons emitted by transitions between energy levels in such "muonic atoms" are easily observed in experiments with muons.
