There is a short lesson how to play the guitar solo of La Bamba by Los Lobos. Originally, La Bamba was a mexican folk song. In the 50's Ritchie Valens made his version and got famous soon. After his early death Los Lobos covered the song and made this cool solo.
Radioactive decay occurs in unstable atomic nuclei â that is, ones that donât have enough binding energy to hold the nucleus together due to an excess of either protons or neutrons.It comes in three main types â named alpha, beta and gamma for the first three letters of the Greek alphabet.Alpha decay. - emission occurs by the transformation of one of the nucleusâs neutrons into a proton, an electron and an antineutrino. Byproducts of fission from nuclear reactors often undergo Î² - decay as they are likely to have an excess of neutrons.
Beta decay occurs when the nucleus emits an electron or positron and a neutrino, in a process that changes a proton to a neutron or the other way about. The nucleus may capture an orbiting electron, causing a proton to convert into a neutron in a process called electron capture.y contrast, there are radioactive decay processes that do not result in a nuclear transmutation. The energy of an excited nucleus may be emitted as a gamma ray in a process called gamma decay, or be used to eject an orbital electron by its interaction with the excited nucleus, in a process called internal conversion.
