Answer» a. False. In some radio nuclides, following beta decay, the gamma ray is not emitted immediately. The radio nuclides before and after emission of the gamma rays are said to be isomers, which have different energy states and half-lives, but the same atomic and mass numbers. b. True. c. False. d. True. e. False. The isomer before the release of the gamma ray is said to be meta stable. |
