If the lifetime for gamma emission exceeds about one nanosecond, the excited nucleus is defined to be in a metastable or isomeric state. The decay process from this excited state is known as an isomeric transition (IT).
Common Law Marriage States. Currently, only nine states (Alabama, Colorado, Kansas, Rhode Island, South Carolina, Iowa, Montana, Oklahoma, and Texas) and the District of Columbia recognize common-law marriages contracted within their borders.
Even when a relationship begins in a state that does not recognize common-law marriage, if the couple relocates to a state that recognizes common-law marriage, a common-law marriage between the parties is often recognized if the couple's relationship continues in the new state.
