A drawn-looking Isabel Peron arrived yesterday to competing chants of "Isabel!" and "witch!" by a rowdy crowd getting the Argentine ex-president's return to Spain after five years under house arrest.

The former chorus girl who succeeded her husband in the presidency in 1974 accepted a bouquet of red roses from the doctor who attended Juan D. Peron during the couple's 13-year exile in Madrid.

But she said nothing to a crowd of about 200, many of them waving the Argentine flag. Friends said she planned no news conferences during her indeterminate stay in Spain. Peron's bodyguards pummelled reporters and photographers pressing afound her car before it sped her away to seclusion in a hotel.

As part of the agreement that led to her release Monday from house arrest in Argentina, Peron, 50,. is not to get involved in politics for the rest of her life. Her friends said that, to avoid any suggestion of politics, she probably would decline an invitation to stay at a villa of Pilar Franco in northern Spain. Franco, eldest sister of the late Spanish dictator Francisco Franco, had lobbied for Peron's release in Buenos Aires and arrived here separately.

Nor was Isabel Peron, still controversial even among Argentina's Peronists, expected to open the mansion outside Madrid where she and her husband planned his short-lived comeback to Argentine politics, achieved in 1973. He died in 1974, and Isabel Peron succeeded him.
