Abstract
We present a theoretical and experimental study on the influence of a magne tic, field on the energy-level statistics in metal nanoparticles. Based on the random-matrix theory, a gradual field-induced crossover behavior is pre dicted from the orthogonal to the unitary ensemble. Experimental data of th e electronic specific heat of metal nanoparticles for different field sin t he quantum size temperature regime compare favorably with these theoretical (analytical) predictions.
