Israeli Foreign Minister Vigal Allon is scheduled to meet with Secretary of State Cyrus R. Vance in London Wednesday, primarily to be briefed on President Carter's meeting with Syrian President Hafez Assad, but Allon can be expected to bring up several issues that are deeply disturbing to Israel, officials said here today.

Allon promised the Cabinet Sunday that he would express to Vance Israel's grave concern over a U.S. proposal that Israel be excluded from a preferred list of countries eligible to receive advanced military technology, weapons and co-production agreements.

Allon can also be expected to ask that the United States refrain from offering Middle East peace suggestions of its own lest they prove harmful to future peace negotiations, officials said.

Israel feels strongly that the shape of peace should be left to the parties themselves to negotiate. They resent any suggestions that the United State might impose its own solution on the Middle East.

Recent statements by Carter and Vance that the United States might be prepared to use pressure to bring about a settlement have worried Israelis. Acting Prime Minister Shimon Peres, however, is anxious to avoid a confrontation with the United States on these matters - especially now with a general election just a week away.

Another source of Israeli concern is the report that President Carter and National Security Adviser Zbigniew Brzezinski discussed with Assad the possibility of demilitarized zones and other security precautions that might be placed between Israel and its Arab neighbors.

Officials stressed that although Israel was not opposed to demilitarized zones, buffers and other types of international guarantees, these measures should be considered only a supplements to - not substitutes for - defensible borders.

Defensible borders, in Israeli terminology, means that Israel should keep some of the Arab territory it captured in the 1967 war. Most Arab leaders have insisted that Israel return everything captured in 1967 and those who have advocated some adjustments, such as Jordan'sKing Hussein, still insist on far more than Israel is now willing to give.

Israeli officials did not rule out the possibility of buffer zones on Israel's side of whatever lines are finally decided upon - a principle that Israel has in the past rejected. But the strong feeling here is that security arrangements should not take the place of substantial, internationally recognized adjustments to the 1967 boundaries in Israel's favor.

Before June 1967, one official said today, "the territory where 75 per cent of our people live could be crossed by a tank brigade in 15 minutes."
