From the reviews:
"This book represents an exhausting monograph on solar neutrons written by an expert who worked about these particles from the Sun since 1965. ... The table of contents is a very detailed one, it covers 24 printed pages. ... Many observations are given in tables and figures, the corresponding theoretical developments are given in many formulas, and subject index and reference list are carefully developed." (Hans-Jürgen Schmidt, Zentralblatt MATH, Vol. 1196, 2010)
