A study of zero-point vacancy effects in quantum solids using                   magnetic techniques developed under previous grant periods will                 be made.  Measurements of zero-point vacancy effects are based on               recent evidence that magnetic polarons may form around ground                   state vacancies in solid 3He.  Quantitative results will be                     sought through measurements of magnetization and pressure as                    functions of density, applied magnetic field, temperature,                      impurity concentration, and sample geometry.  The results will be               analyzed and compared with theoretical calculations that remove                 some deficiencies of existing polaron models and with predictions               based on improved stability criteria of polarons in the                         paramagnetic phase.
