Abstract
Growth of helium bubbles in palladium, having different pre-irradiatio n sample treatments and subsequently implanted with 50 appm of helium, has been investigated by positron lifetime spectroscopy. Presence of dislocations has been found to enhance the density of nucleated bubble s. A suppression of helium bubble growth due to the presence of disloc ations is established. Bubble growth is reduced by over-pressure in di slocation-containing samples.
