President Carter continued his review of domestic issues in the seclusion of Camp David yesterday, meeting throughout the afternoon with a diverse group of individuals for what White House press secretary Jody Powell Described as a "freewheeling discussion" of energy issues.

"It will all become clear by and by, as the old hymn goes," Powell said yesterday when asked about the details of the talks and "carter's intention in convening the extraordinary "domestic summit conference."

White House officials made public a list of those who met with Carter yesterday, and said that president will meet today with two groups of member of "congress, the first in the morning for a discussion of energy and the second in the afternoon for talks on inflation and the economy.

Beyond these details, the talks continued behind a cloak of secrecy. Senior Carter advisers insisted yesterday that the president knows exactly what he wants to accomplish in the meetings at the presidential retreat in Maryland's Catoctin Mountains, and they seemed unconcerned by the public attention the unusual format has drawn and the expectations it has aroused.

The Camp David meetings now are scheduled to last at least through Wednesday. Carter's plans after that are unclear. But White House officials said that the president clearly will have to report to the nation shortly after the talks conclude, possibly in the form of a nationally televised address similar to the one he abruptly canceled last week when he convened the conference.

Carter began the Camp David discussions, first with his own political advisers, last Thursday at a low point in his personal popularity and political support. His problems are mainly domestic, beginning with the gasoline lines but also including a continued high rate of inflation and, with the latest boost in world oil prices, the clear prospect of a recession.

For several days Powell has stressed to reporters that Carter wished to examine the nation's energy situation -- his most pressing problem -- in "a broader context" than heretofore. But he steadfastly has refused to elaborate on that cryptic description of the president's intentions, saying only that the intentions would become clear when the Camp David talks end.

Yesterday, according to Powell, the focus of the talks shifted from the "broader context" to energy specifics, including a discussion of measures to reduce U.S. oil imports and to manage the shortage that has produced gasoline lines.

For the first time, Energy Secretary James R. Schlesinger Jr. -- whose job has been rumored to be in jeopardy because of the energy situation joined the talks. Carter's chief domestic policy adviser, Stuart E. eizenstat, also took part, Powell said.

The diverse group included three Democratic governors -- Hugh Gallen of New Hampshire, Robert Graham of Florida and John D. (Jay) Rockefeller IV of West Virgina -- and Rep. Lindy Boggs (D-La.), chairman of the House Energy appropriations subcommittee.

The others, all flown to Camp David by helicopter, were Jim Akins, an international oil consultant and former ambassador to Saudi Arabia; Thornton Bradshaw, president of atlantic-Richfield; David Freeman, chairman of the Tennessee Valley Authority; Russell Peterson, president of the National Audubon Society; John Sawhill, former head of the Federal Energy Administration and now president of New York University; Martin Ward, president of the Plumbers Union and the AFL-CIO's chief energy coordinator; and Jerome Weisner, president of the Massachusetts "institute of Technology.

House Speaker Thomas P. (Tip) O'Neill Jr. (D-Mass.) and Senate Majority Leader Robert C. Byrd (D-W.Va.) will be among the members of Congress who meet with Carter today. Treasury Secretary W. Michael Blumenthal and possibly other administration economic advisers also will join today's talks on the economy, Powell said.

The presidential spokesman, however, said that "major actions" to deal with the economy, particularly the threat of a recession, should not be expected from the Camp David talks. He said the president agrees with his economic advisers that it is too early to decide what action -- a tax cut, for example -- should be taken to deal with the recession threat.

The people Carter has conferred with at Camp David all have described him as being in "an upbeat mood," apparently not discouraged by his political problems from the energy shorgage.

Civil rights leader Jesse Jackson, one of a small group that spent Saturday night at Camp David, said that when the president reports on the talks "there will be a tremendous challenge for this country for some major, structural readjustments."

"We have an energy crisis, an urban crisis, growing racial polarization . . . a morale crisis," Jackson said. "You get all of these together and you have a civilization crisis. And that calls for radical and major reassessments. So the president is decisive about that. He is preceptive about that."
