Дано опис парно-парних iзотопiв паладiю для A вiд 102 до 106 в моделi взаємодiючих бозонiв (МВБ). Розрахованi низьколежачi iраст-смуги з позитивною парнiстю i вiдповiднi величини B(E2), що добре узгоджуються з експериментом. З використанням спрощеного варiанта МВБ з власним когерентним станом вивченi контурнi графiки поверхнi потенцiальної енергiї. Знайдено критичнi точки для 102Pd iзотопу i обґрунтовано O(6) симетрiю для 104,106Pd.
