question: Which Particle has an Isospin I of 1 and Commonly decays to p + + π 0 or n 0 + π +?
answer: SELECT particle FROM table_name_41 WHERE isospin_i = "1" AND commonly_decays_to = "p + + π 0 or n 0 + π +"
context: CREATE TABLE table_name_41 (particle VARCHAR, isospin_i VARCHAR, commonly_decays_to VARCHAR)
