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.
A valid common law marriage in Texas is where a man and woman become husband and wife without getting a marriage license and having a marriage ceremony. Once established, a common law marriage has the same legal effect as a ceremonial marriage.
