Question 6: Radioactivity (See textbook Chapter 6 - Exercise 6) Cf has a half-life of 2.64 years. It disintegrates by a-emission in 96.9% of the events and by spontaneous fission in 3.1%. a) What is its mean lifetime? b) What is the ratio between the number of a-particles and number of fissions produced? c) What half-life would this isotope have if it did not have spontaneous fission?
