CONTENTS. After a radioactive nucleus undergoes an isobaric transition (beta emission, positron emission, or electron capture), it usually contains too much energy to be in its final stable or daughter state. Nuclei in these intermediate and final states are isomers, since they have the same atomic and mass numbers.
In the fall, it was widely reported that people from four U.S. states may need a passport to fly domestically this year. Now, the Department of Homeland Security has increased the list of U.S. locations not offering state driverâs licenses that comply with new federal regulations known as the Real ID Act.
In most states, picture IDs issued by the government are considered valid forms of ID. This includes driver's licenses, photo driver permits and state issued non-driver identification cards. The exact form of valid ID that is acceptable depends on the use and the organization in question. For instance, in Tennessee, to obtain a driver's license, a certified birth certificate, a military ID and unexpired passports are considered valid forms of identification. Citizen documentation, marriage licenses and divorce decrees are valid IDs in that state. For the majority of standardized tests such as the ACT, the only forms of valid ID accepted are photo driver's license or any other photo identification issued by the state, the federal government or a school.
