Description

Volume and surface electron density of ultrafine particles of nickel with the mean diameter 500 A was investigated by means of positron lifetime spectroscopy. Defect and surface capture rates were calculated basing on capture model. It was found that surface electron density variates unmonotonously with increase of pressure. Baking leads to the void formation in the samples
