Nuclear fusion of integer spin nuclei confined in an isotropic ion trap is
investigated. Solutions of the ground state for charged bosons trapped in t
he isotropic harmonic oscillator potential are calculated using the equival
ent linear two-body method for many-body problems, which is based on an app
roximate reduction of the many body Schrodinger equation by the use of a va
riational principle. Using the ground-state wavefunction, theoretical estim
ates of probabilities and rates for nuclear fusion for Bose nuclei confined
in ion traps are obtained. Numerical estimates for fusion rates are presen
ted for the case of deuteron-deuteron fusion.
