How do you know what decay products are produced? A very good question! Go here after reading the rest of the paragraph. You will be looking at a mass distribution curve for the SF of Cf-252. WebNov 29, 2014 · Californium-252 (Z = 98) is valued as a potent neutron source due to its spontaneous fission decay path. Thin film sources containing Cf-252 were prepared by two techniques: evaporation and self-transfer. The sources were analyzed by alpha and gamma spectroscopy. Results indicate that self-transfer sources exhibit less alpha energy … acriflavine solution in bangladesh 252 Cf synth 2.645 y: α 96.9%: 248 Cm ... 249 Cf is formed from beta decay of berkelium-249, ...
