Variational Calculation of Low-energy Positron Life Time in Xe Atoms
Positron Annihilation Bound wavefunction Scattered wavefunction Variational Method
2010/6/30
The least-squares variational method (LSVM) is used for determining trial wavefunctions representing lowenergy positron-xenon elastic scattering, which are used to determine the positron lifetime. The...

We investigate the quantum Zeno effect in the case of electron tunneling out of a quantum
dot in the presence of continuous monitoring by a detector. It is shown that the Schr¨odinger
equation for t...
