Popis: Growth of helium bubbles in palladium, having different pre-irradiation 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 bubbles. A suppression of helium bubble growth due to the presence of dislocations is established. Bubble growth is reduced by over-pressure in dislocation-containing samples.
