Quantum states of deuterons in Pd

摘要

Many deuterons can be accumulated in Pd. If the local density of deuterons at Pd lattice defects becomes high enough, Bose -Einstein condensation (BEC) may happen and induce nuclear reactions. In this work, nuclear reactions in Pd induced by BEC are estimated. The equivalent linear two-body (ELTB) method, which is based on an approximate reduction of many-body problems by variational principle, is used for the calculation. Thomas-Fermi and non-linear screening d-d interactions are used for the calculations. The nuclear reaction rates and critical temperatures of BEC are obtained from the ELTB solutions.
