The controversy over some Pakistan nuclear scientists collaborating with countries listed as "axis of evil" by the US has deepened further with the media in Islamabad publishing on Wednesday contents of a brochure allegedly brought out by by the country's top nuclear scientist, Dr Abdul Qadeer Khan, offering nuclear technology to other nations.

The information that Dr Khan has been offering nuclear and nuclear related technology to other nations was in circulation in Washington as early as December, a local daily said.

In a Washington datelined story, The Dawn said last month it had received a copy of the pamphlet purportedly
distributed by the A Q Khan Research Laboratories, offering vacuum technology for sale.

The pamphlet has a Rawalpindi address, P.O. Box 502, and has pictures of the equipment it offers. It also has a
picture of Dr Khan on the extreme right corner wearing the medals awarded by the government of Pakistan.

Dr Khan was in-charge of Pakistan's nuclear programme till last year. He retired after President Prevez Musharraf did not extend his tenure allegedly under pressure from the United States. He was subsequently made scientific advisor to Musharraf. 

A message distributed with the pamphlet said: "Besides manufacturing vacuum components and systems, our vacuum
constancy services are also available for system design, operational troubleshooting, quality assurance, maintenance,
system development and human resource training."

In 1998, Ernest Piffl, managing director of the German firm "GmbH" near Stuttgart received a three-and-half-year sentence for illegally exporting thousands of performs for gas centrifuge scoops to Pakistan's secret uranium enrichment
programme.

"Performs are partially finished cast or machined components and the ones sent to Pakistan were made of a
special aluminium alloy and looked like small thin-wall pipes. Bending and finishing these little pipes would have
been done at the point of assembly of the centrifuge," the newspaper report said.

This centrifuge technology that Dr Khan learned while working at a nuclear plant in Holland is the same as the
vacuum technology the A Q Khan Research Laboratories was selling, it added.

Pakistan has vehemently denied the allegations.
