The Quantum Mechanics of Alpha Decay
ثبت نشده
چکیده
The purpose of this experiment is to explore the relation between the mean lives of alpha-active nuclides and the energies of the alpha particles they emit. You will study portions of the sequences of radioactive transformations whereby uranium is transmuted into lead. Various procedures will be used to measure the alpha-particle energies and lifetimes of five alpha-active nuclides with mean lives ranging from days to microseconds, as well as the mean lives of two beta-active nuclides.

متن کاملQuantum Mechanics and the Mechanism of Sexual Reproduction
There are many claims that quantum mechanics plays a key role in the origin and/or operation of biological organisms. The mechanism of the meiosis, mitosis and gametes life cycle from the view-point of quantum for human has been represented. The quantum gates have been used to simulate these processes for the first time. The reason of several hundred sperms has been explained in the male too
متن کاملQuantization of electromagnetic fields in the presence of a spherical semiconductor quantum dot and spontaneous decay of an excited atom doped in this nanostructure
In this paper we consider electromagnetic field quantization in the presence of a dispersive and absorbing semiconductor quantum dot. By using macroscopic approach and Green's function method, quantization of electromagnetic field is investigated. Interaction of a two-level atom , which is doped in a semiconductor quantum dot, with the quantized field is considered and its spontaneous emission ...

متن کاملStructure-Activity Relationship of Imidazobenzodiazepines, an AM1 Semi-Empirical Quantum Mechanics Study
Conformations and electronic properties of a series of imidazobenzodiazepines are investigated by AM1 semi-empirical quantum mechanics method. It is shown that substitution of Cl in position 7 instead of 8, changes the geometry of the seven membered lactam ring; this may put the N5 nitrogen in a better positon to act as a hydrogen bond acceptor, and the phenyl ring in position 6 is probably...
