The isomeric 2+ state of 60co at 58.6 kev decays to the 5+ ground state. internal conversion competes with gamma emission: the observed internal conversion coefficients are alphak=41, alphal=7 and alpham=1. compute the expected half-life of the 2+ state if the tranition multipolarity is assumed to be m3 and compare it with the observed half-life. if the transition also contained a small component of e4 radiation, how would your estimate for the half-lif be altered? the 2+ state also decays by direct beta emission to 60ni. the maximum beta energy is 1.55 mev and the log(ft1/2) is 7.2. what is the effect of having this additional mode of decay? how much of each decay would we see and what would happen o the half-life?

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
